Key Benefits Long-Range, Cost-Effective Wireless Connectivity Between Sitesbuildings, portable or temporary classrooms, and temporary networks. And if your company’s network requirements or location change, the wireless building-to-building bridge can be easily relocated.High PerformanceWith our wireless building-to-building bridge, you get high-speed, long-range connections. In fact, you’ll get throughput exceeding that of two dedicated T1 lines. Plus, you won’t have to worry about expensive leased-line service that’s actually slower than this wireless bridge.Flexible ConnectionsWith point-to-point and point-to-multipoint connectivity options, our wireless building-to-building bridge lets you transfer information between two buildings or multiple buildings across campus. What’s more, you can choose the antenna option that best fits your needs—get transmissions up to 1300 meters with omni-directional antennas, and 4100 meters using sector panel antennas.Figure 1. Point-to-multipoint connections fromone to multiple buildings using omni-directional antennas.Figure 2. Point-to-point connections from one building to another using sector panel antennas.Simple ManagementThe easy-to-use graphical interface reduces management burdens. Manage all of your bridges from anywhere on the same subnet, or do it over the Internet using telnet. Easily align antennas with real-time signal strength reporting and usage data. Plus, default settings make configura-tion simple—all you have to do is hook them up.Complete SecurityWhen you choose our wireless building-to-building bridge, you don’t have to worry about security. Support for both 40- and 128-bit WEP encryp-tion lets users exchange information privately. Plus, our bridge uses a3Com proprietary protocol to encapsu-late data. This protocol ensures the wireless bridge will not interfere with VPN or other protocols—so your encrypted data passes right through. Cost EffectiveNow you can connect all of those hard-to-wire locations for less. With our building-to-building bridge, you don’t have to worry about running expensive and tough-to-install leased lines or fiber-optic cabling. Just connect your wired LANs to wireless building-to-building bridges, or connect a remote building-to-building bridge to a 3Com 11 Mbps Wireless LAN access point. In minutes, you’ve interconnected a remote site with the central site. Best yet, this hardware investment can pay for itself, when compared to the money you would have spent on leased-line service.2Networking on a Tight Budget When to BuyOur building-to-building bridge isideal for organizations who:•Are looking for a cost-effectivealternative to leased lines.•Don’t want to invest in layingexpensive and tough-to-installcables since their network require-ments or location may change.•Want a simple way to connectremote and hard-to-wire locations—between office buildings that aren’talready connected to one another,portable classrooms and cross-cam-pus office buildings, and buildingsseparated by other structures suchas bridges or freeways.One-Year Limited Warranty3Com warrants your wirelessbuilding-to-building bridge to be ingood working order for one yearwhile owned by the original end user.Customer SupportQuick access to support informationis available on 3Com’s Web site atJill, a fictional principal for FairmontHigh, is excited for the schooladdition—three computer labs, 15classrooms, and more. But that’s twoyears off. Classrooms are bursting atthe seams. More students are on theway. And 50 new computers need to benetworked. Is it possible on theschool’s budget? Yes.Using our building-to-buildingbridges, she turned one of three newportable classrooms into a computer laband gave the others network access—without running cables. She connectedone bridge to the school network andanother to an access point in theportable computer lab. Now all of thenew computers, including those inportable classrooms, have access tonetwork resources and the Internet.Just like you’d expect—a simplesolution from 3Com.3Product Features802.11b Data Rates Supported 11, 5.5, 2, 1 MbpsRangeTransmit and receive informa-tion up to 4100 meters between wireless building-to-building bridges, depending on the antenna selected.Network StandardIEEE 802.11bNetwork Connection Type10BASE-TNetwork Architecture Types Bridge 802.3 to 802.11bNumber of Users/Bridge UnlimitedWireless Bridges/LAN Unlimited Frequency Band2.4 GHzWireless MediumDSSSMedia Access ProtocolCSMA/CAModulationDSSSOperating Channels1 through 11 (U.S.)Receive Sensitivity11 Mb: -81 dBm5.5 Mb: -84 dBm2 Mb: -85 dBm1 Mb: -87 dBmAvailable Transmit PowerSettings300 mw, typicallyAntennaMultiple antenna options letyou ensure the optimal signalstrength for your environment.Encryption40- and 128-bit WEPencryption, shared keySecurityVPN pass throughLEDsPower: greenWireless: green whenassociated; yellow whentransmitting/receivingEthernet: green whenconnected; yellow when activityis detectedAlert: amberSerial: green when RX; yellowwhen TXSpecifications43Com Corporation, 5400 Bayfront Plaza, P .O.

High Efficiency 800mA Single Channel Linear WLED Driver with Ultra Fast PWM™ Control
General Description
The MIC4802 is a high efficiency White LED (WLED) driver designed to drive a single LED up to 800mA. The MIC4802 constant current driver is designed to drive high power LED’s in various lighting applications. The MIC4802 provides the highest possible efficiency as this architecture has no switching losses present in traditional charge pumps or inductive boost circuits. It features a typical dropout of 280mV at 800mA. This allows the LEDs to be driven directly from the voltage source eliminating switching noise/losses present with the use of boost circuitry. The high accuracy (±1% Typical) current regulated WLED channel ensures uniform display illumination under all conditions. The brightness is controlled through an Ultra Fast PWM™ Control interface operating down to less than 1% duty cycle.

PULL-DOWN RESISTOR ON THE RS-232 INPUT.C30.1µFC20.1µFC10.1µFFigure 1.GENERAL DESCRIPTIONThe ADM3251E is a high speed, 2.5 kV fully isolated, single-channel RS-232/V.28 transceiver device that operates from a single 5 V power supply. Due to the high ESD protection on the R IN and T OUT pins, the device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently being plugged and unplugged.The ADM3251E incorporates dual-channel digital isolators with iso Power? integrated, isolated power. There is no requirement to use a separate isolated dc-to-dc converter. Chip-scale trans-former i Coupler? technology from Analog Devices, Inc., is used both for the isolation of the logic signals as well as for the integrated dc-to-dc converter. The result is a total isolation solution. The ADM3251E conforms to the EIA/TIA-232E and ITU-T V. 28 specifications and operates at data rates up to 460 kbps.Four external 0.1 µF charge pump capacitors are used for the voltage doubler/inverter, permitting operation from a single5 V supply.The ADM3251E is available in a 20-lead, wide body SOIC package and is specified over the ?40°C to +85°C temperature range.ADM3251ERev.

Functional Block DiagramISOLATION OF POWER AND DATAThe ADM3251E incorporates a dc-to-dc converter section, which works on principles that are common to most modern power supply designs. V CC power is supplied to an oscillating circuit that switches current into a chip-scale air core transformer. Power is transferred to the secondary side, where it is rectified to a high dc voltage. The power is then linearly regulated to about 5.0 V and supplied to the secondary side data section and to the V ISO pin. The V ISO pin should not be used to power external circuitry.Because the oscillator runs at a constant high frequencyindependent of the load, excess power is internally dissipated in the output voltage regulation process. Limited space for transformer coils and components also adds to internal power dissipation. This results in low power conversion efficiency. The ADM3251E can be operated with the dc-to-dc converter enabled or disabled. The internal dc-to-dc converter state of the ADM3251E is controlled by the input V CC voltage. In normal operating mode, V CC is set between 4.5 V and 5.5 V and the internal dc-to-dc converter is enabled. When/if it is desired to disable the dc-to-dc converter, lower V CC to a value between 3.0 V and 3.7 V . In this mode, the user must externally supply isolated power to the V ISO pin. An isolated secondary side voltage of between 3.0 V and 5.5 V and a secondary side input current, I ISO , of 12 mA (maximum) is required on the V ISO pin. The signal channels of the ADM3251E then continue to operate normally.The T IN pin accepts TTL/CMOS input levels. The driver input signal that is applied to the T IN pin is referenced to logic ground (GND). It is coupled across the isolation barrier, inverted, and then appears at the transceiver section, referenced to isolated ground (GND ISO ). Similarly, the receiver input (R IN ) accepts RS-232 signal levels that are referenced to isolated ground. The R IN input is inverted and coupled across the isolation barrier to appear at the R OUT pin, referenced to logic ground. The digital signals are transmitted across the isolation barrier using i Coupler technology. Chip-scale transformer windings couple the digital signals magnetically from one side of the barrier to the other. Digital inputs are encoded into waveforms that are capable of exciting the primary transformer of the winding. At the secondary winding, the induced waveforms are decoded into the binary value that was originally transmitted. There is hysteresis in the V CC input voltage detect circuit. Once the dc-to-dc converter is active, the input voltage must be decreased below the turn-on threshold to disable the converter. This feature ensures that the converter does not go into oscillation due to noisy input power.ADM3251ERev. A | Page 12 of 1607388-0144.5VFigure 14. Typical Operating Circuit with the DC-to-DC Converter Enabled(V CC = 4.5 V to 5.5 V)07388-0153.0V TO 5.5VFigure 15. Typical Operating Circuit with the DC-to-DC Converter Disabled(V CC = 3.0 V to 3.7 V)CHARGE PUMP VOLTAGE CONVERTERThe charge pump voltage converter consists of a 200 kHz oscillator and a switching matrix. The converter generates a ±10.0 V supply from the input 5.0 V level. This is done in two stages by using a switched capacitor technique as illustrated in Figure 16 and Figure 17. First, the 5.0 V input supply is doubled to 10.0 V by using C1 as the charge storage element. The +10.0 V level is then inverted to generate ?10.0 V using C2 as the storage element. C3 is shown connected between V+ and V ISO , but is equally effective if connected between V+ and GND ISO . Capacitors C3 and C4 are used to reduce the output ripple. Their values are not critical and can be increased, if desired. Larger capacitors (up to 10 µF) can be used in place of Capacitors C1, C2, C3, and C4.ISOV ISO07388-016Figure 16. Charge Pump Voltage DoublerISOV– = –(V+)07388-017Figure 17. Charge Pump Voltage Inverter5.0 V LOGIC TO EIA/TIA-232E TRANSMITTERThe transmitter driver converts the 5.0 V logic input levels into RS-232 output levels. When driving an RS-232 load with V CC = 5.0 V , the output voltage swing is typically ±10 V .EIA/TIA-232E TO 5 V LOGIC RECEIVERThe receiver is an inverting level-shifter that accepts the RS-232 input level and translates it into a 5.0 V logic output level. The input has an internal 5 kΩ pull-down resistor to ground and is also protected against overvoltages of up to ±30 V . An uncon-nected input is pulled to 0 V by the internal 5 kΩ pull-down resistor. This, therefore, results in a Logic 1 output level for an unconnected input or for an input connected to GND. The receiver has a Schmitt-trigger input with a hysteresis level of 0.1 V . This ensures error-free reception for both a noisy input and for an input with slow transition times.HIGH BAUD RATEThe ADM3251E offers high slew rates, permitting data trans-mission at rates well in excess of the EIA/TIA-232Especifications. The RS-232 voltage levels are maintained at data rates up to 460 kbps.THERMAL ANALYSISEach ADM3251E device consists of three internal die, attached to a split-paddle lead frame. For the purposes of thermal analysis, it is treated as a thermal unit with the highest junction temper-ature reflected in the θJA value from Table 7. The value of θJA is based on measurements taken with the part mounted on a JEDEC standard 4-layer PCB with fine-width traces in still air. Following the recommendations in the PCB Layout section decreases the thermal resistance to the PCB, allowing increased thermal margin at high ambient temperatures.ADM3251ERev. A | Page 13 of 16PCB LAYOUTBecause it is not possible to apply a heat sink to an isolation device, the device primarily depends on heat dissipating into the PCB through the GND pins. If the device is used at high ambient temperatures, care should be taken to provide a thermal path from the GND pins to the PCB ground plane. The board layout in Figure 18 shows enlarged pads for Pin 4, Pin 5, Pin 6, Pin 7, Pin 10, and Pin 11. Multiple vias should be implemented from each of the pads to the ground plane, which significantly reduce the temperatures inside the chip. The dimensions of the expanded pads are left to the discretion of the designer and the available board space.The ADM3251E requires no external circuitry for its logic interfaces. Power supply bypassing is required at the input and output supply pins (see Figure 18).The power supply section of the ADM3251E uses a 300 MHz oscillator frequency to pass power through its chip-scale trans-formers. In addition, the normal operation of the data section of the i Coupler introduces switching transients on the power supply pins. Low inductance capacitors are required to bypass noise generated at the switching frequency as well as 1 ns pulses generated by the data transfer and dc refresh circuitry. The total lead length between both ends of the capacitor and the input power supply pin should not exceed 20 mm.INSULATION LIFETIMEAll insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. The rate of insula-tion degradation is dependent on the characteristics of the voltage waveform applied across the insulation. In addition to the testing performed by the regulatory agencies, Analog Devices carries out an extensive set of evaluations to determine the lifetime of the insulation structure within the ADM3251E. In cases where EMI emission is a concern, series inductance can be added to critical power and ground traces. Discrete inductors should be added to the line such that the high frequency bypass capacitors are between the inductor and the ADM3251E device pin. Inductance can be added in the form of discrete inductors or ferrite beads added to both power and ground traces. The recommended value corresponds to impedance between 50 Ω and 100 Ω at approximately 300 MHz.The insulation lifetime of the ADM3251E depends on the voltage waveform type imposed across the isolation barrier. The i Coupler insulation structure degrades at different rates depending on whether the waveform is bipolar ac, unipolar ac, or dc. Figure 19, Figure 20, and Figure 21 illustrate these different isolation voltage waveforms.In applications involving high common-mode transients, care should be taken to ensure that board coupling across the isolation barrier is minimized. Furthermore, the board layout should be designed such that any coupling that does occur equally affects all pins on a given component side. Failure to ensure this can cause voltage differentials between pins to exceed the absolute maximum ratings of the device, thereby leading to latch-up and/or permanent damage.Bipolar ac voltage is the most stringent environment. In the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower.0VRATED PEAK VOLTAGE 07388-019V CC V CCGND V ISOV+。

ADM483E GENERAL INFORMATIONThe ADM483E is a robust RS-485 transceiver that operates from a single 5 V supply.It is ideally suited for operation in electrically harsh environ-ments or where cables may be plugged and unplugged. It is also immune to high RF field strengths without special shielding precautions. The ADM483E is intended for balanced data transmission and complies with both EIA Standards RS-485 and RS-422. It contains a differential line driver and a differential line receiver; it is suitable for half-duplex data transmission because the driver and receiver share the same differential pins. The input impedance on the ADM483E is 12 kΩ, allowing up to 32 transceivers on the differential bus.The ADM483E operates from a single 5 V ± 10% power supply. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. This feature forces the driver output into a high impedance state if, during fault conditions, a significant temperature increase is detected in the internal driver circuitry.The receiver has a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating).A high level of robustness is achieved using internal protection circuitry, eliminating the need for external protection components such as transorbs or surge suppressors.Low electromagnetic emissions are achieved using slew limited drivers, minimizing interference both conducted and radiated. The ADM483E can transmit at data rates up to 250 kbps.A typical application for the ADM483E is illustrated in Figure 23. This figure shows a half-duplex link where data may be transferred at rates up to 250 kbps. A terminating resistor is shown at both ends of the link. This termination is not critical because the slew rate is controlled by the ADM483E and reflections are minimized.The communications network can be extended to include multipoint connections as shown in Figure 26. Up to 32 transceivers can be connected to the bus.612-23 Figure 23. Typical Half-Duplex Link ApplicationTable 6 and Table 7 show the truth tables for transmitting and receiving.1 X = don’t care.1 X = don’t care.ESD TRANSIENT PROTECTION SCHEMEThe ADM483E uses protective clamping structures on its inputs and outputs that clamp the voltage to a safe level and dissipate the energy present in ESD (electrostatic discharge).The protection structure achieves ESD protection up to ±15 kV according to the Human Body Model.ADM483ETYPICAL PERFORMANCE CHARACTERISTICS510152025303540455000.5 1.0 1.5 2.0 2.5OUTPUT LOW VOLTAGE (V)O U T P U T C U R R E N T (m A)06012-003Figure 3.

General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, andMAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and onereceiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize E MI andreduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them totransmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA ofsupply current when unloaded or fully loaded with disableddrivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consumeonly 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature thatguarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-loadreceiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, whilethe MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________Applications Low-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level Translators Transceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features o For Fault-Tolerant Applications MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 Transceiver MAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers o For Space-Constrained Applications MAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 Transceivers MAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 Package MAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe Receivers MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-485/RS-422 Transmitters o For Multiple Transceiver Applications MAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters o For Fail-Safe Applications MAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceiverso For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kVESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 Transceivers For pricing, delivery, and ordering information, please contact Maxim Direct at1-888-629-4642, or visit Maxim Integrated’s website at .______________________________________________________________Selection Table19-0122; Rev 10; 9/14PARTNUMBERHALF/FULL DUPLEX DATA RATE (Mbps) SLEW-RATE LIMITED LOW-POWER SHUTDOWN RECEIVER/DRIVER ENABLE QUIESCENT CURRENT (μA) NUMBER OF RECEIVERS ON BUS PIN COUNT MAX481Half 2.5No Yes Yes 300328MAX483Half 0.25Yes Yes Yes 120328MAX485Half 2.5No No Yes 300328MAX487Half 0.25Yes Yes Yes 1201288MAX488Full 0.25Yes No No 120328MAX489Full 0.25Yes No Yes 1203214MAX490Full 2.5No No No 300328MAX491Full 2.5No No Yes 3003214MAX1487 Half 2.5No No Yes 2301288Ordering Information appears at end of data sheet.找电子元器件上宇航军工MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-LimitedRS-485/RS-422 TransceiversPackage Information For the latest package outline information and land patterns, go to .

Description
4:1 Input * add suffix /H4 for 4kVDC isolation or /H6 (REC3-S/DRWZ(H4/H6)) for 6kVDC isolation xx = 9-36Vin = 24 * add suffix "/A" or "/C" for Pinning, see next page xx = 18-72Vin = 48 “B” Pinning is NOT available for this series ! * add suffix "/M" for metal case * add suffix "/SMD" for SMD package e.g. REC3-2412SRW/H4/AM = 4kVDC isol. / Pinout "A" / metal case
Notes :
1. If the options "/M" for metal case and "/SMD" for SMD pinout are combined, the maximum allowed isolation voltage is 2kVDC because of the shorter distances between pins and the metal case, so only available SMD-option in metal-case is "/H2". DIP-24 through-hole case and SMD-plastic case are not affected and offer the full isolation barriers of 4kVDC for "/H4" option and 6kVDC for "/H6".

It features a powerful gear reduction motor that pulls a moveable blade through the toughest copper and aluminum cables.The REC-50M comfortably fits into the lineman’s gloved hand, and repetitive ratcheting movement is entirely eliminated. Just a squeeze of the rocker arm trigger is all it takes to make a cut and almost no muscle power is needed. As a result, the risk of sprains, strains, and lost time due to muscle related injuries can be significantly reduced. The moveable blade has wide gear teeth for extra power and full cutting traction. Gear guides are attached on both ends of the movable blade to align the gear teeth with the internal pinion gear.OPERATING INSTRUCTIONS CHARGING THE BATTERY1. Insert the plug end into a 120V power source. The LED (Power) indicator willbe steady green indicating the charger is now in “stand-by” mode and ready tocharge the battery. Do not plug the charger into a generator as this will likelycause the fuse in the charger to short, and will not operate.2. To charge a drained battery, insert the battery into the charger. The LEDindicator shows a steady amber while charging. A depleted battery will becompletely charged in approximately 50-70 minutes. The LED indicator will showa steady green when the battery is fully charged.3. If the LED indicator goes out or is flashing quick amber, this could be a possibleshort in the battery circuit, or a problem with the charger itself. It is best to consultthe factory at 1-800-860-6170 for service if such a condition occurs.4. For technical questions or difficulty in operation, please call our customerservice department at 1-800-860-6170.ATTACHING THE BATTERY CARTRIDGE1. While pressing the latch, pull out the battery cartridge. T o replace the batterycartridge, push the new cartridge firmly into place.2. After inserting a battery cartridge, check that it is securely inplace by pulling gently. Do not press the latch when pulling the cartridge.TRIGGER AND RELEASE BUTTON1. The ram advances when the trigger is pressed and stops when the trigger isreleased.2. To retract the ram, push the release button. The ram continues to retract whilethe release button is pressed.CUTTING1. Retract blades by pressing the release button.2. Be sure that material being cut is within the specified cutting capacity of the tool.3. Place the material to be cut between the blades and press the advance trigger until blades hold the material in place.4. Check material for proper alignment to the cutting blades. It should be at a 90° degree angle to the blades. Any other angle will cause the blades to spread apart and possibly break.5. Continue to advance the blades until the material is cut. If material is cut and tool has not yet by passed, it may be difficult to retract blades. If this occurs, continue to advance tool and build pressure. A series of clicks will be heard while the tool running in a “neutral” mode. This indicates that the tool has built full pressure and bypassed and can now be released.MAINTENANCE AND INSPECTION1. Daily maintenance is required to ensure that the tool is kept in good working condition.2. Sharpen blades occasionally with a sharpening stone on the back side of the blades to remove any burrs that may occur.3. Do not store the tool in a humid environment.4. Wipe away any excess oil with a soapy cloth.5. Provided that maintenance of the tool is carried out regularly, the tool should providemany years of service.6. Should you experience any difficulty with the operation and maintenance of this tool,contact Huskie’s technical support department at 1-800-860-6170.PRECAUTION FOR THE TOOLPRECAUTION FOR THE CHARGER1. Select appropriate dies for the connector to be compressed. Incorrect combinations result in inferior connections of the conductors. Consult your connector manufacturer for the recommended die/connector combinations.2. Always point the tool AWAY from other people.3. If the tool is stored for an extended period at a temperature of less than 25º F (-5ºC), the tool should be allowed to return to room temperature to ensure smooth operation Use the tool only after it has been at room temperature for 1 hour.4. Do not drop the tool. Dropping the tool may damage the hydraulic circuit and result in the tool not functioning correctly.5. Keep the head and ram clean and free of debris. Solvents can be used to clean the head, but should not be used on the plastic body. Use soap and water to clean the body.6. Do not use tool for continous use. If any sign of over heating, allow the tool to cool for 15 mins.7. Do not allow tool to be submerged in water. The tool may be used in damp or wet environ-ments. However it is recommended for tool to be air-dried before use.PRECAUTION FOR THE BATTERY CARTRIDGE1. Do not short circuit the contacts or expose the cartridge to water, oil or solvents.2. Do not disassemble or attempt to repair the battery cartridge or dispose of in a fire.3. Do not drop or otherwise abuse the battery cartridge.4. Do not leave the cartridge in locations where it will be exposed to a temperature greater than 140ºF (60ºC) for an extended period.5. The battery has a limited life. When the crimping capacity becomes about 1/2 that of the original capacity, the battery should be replaced.6. If the battery cartridge is stored without being charged, natural drainage will cause the power to be reduced. The battery should be charged every 3 months if not in use.1. The LED indicator lights up amber and remains lit when the unit starts charging a battery cartridge. The indicator turns green when charging is completed.2. The BP-84 can be charged with any of the Huskie Lithium-Ion chargers including the CH-80, CH-90 & CH-94.3. Allow battery cartridges to cool before charging. Allow at least 15 minutes between charges when charging several cartridges in succession.4. Charge batteries at an ambient temperature of 50º-95ºF (10º-35º C). Charging time is approximately 50-70 minutes for the BP-84.5. Never short circuit the output terminals.6. Do not expose the charger to water, oil or solvents.7. Do not disassemble, attempt to modify, drop or otherwise abuse charger.BREAKDOWNPARTS LISTNO.DESCRIPTION CODE QTY.11 M3 X 3 Screw RC50-03 212 Gear Guide (B) RC50-04 113 Moving Blade RC50-16 114 Shoulder Screw RC50-05 115 Gear Guide (A) RC50-15 116 Stationary Blade RC50-18 117 M6 Lock Washer (Ni) RC50-06 118 M6 Lock Nut RC50-07 119 M3 X 8 Screw RC50-08 520 Bearing Case RC50-10 121 Cutter Plate RC50-11 122 M5 X 14 Screw RC50-09 1123 Bearing 6001 RC50-12 124 Pinion Gear RC50-13 125 Bearing 6002 RC50-14 126 Needle Pin 3 X 11.8 RC50-17 227 Gear Case Ass'y RC50-19 128 M4 X 8 Screw RC50-20 229 Gear RC50-21 130 Gear Plate RC50-22 231 Gear Cover RC50-23 132 Housing Set 50M-HS 133 Hanging Strap 558-0７A 134 M3 X 14 Screw (T.P.)
