ENERAL SAFETY MESSAGES AND WARNINGS
All instructions and safety messages in this manual must be followed to allow safe installation of the device. The device must only be installed and maintained by correctly trained site personnel/installers. See also certified annex for special conditions for safe use.
•To reduce the risk of ignition of hazardous atmospheres and shock, do not apply power to the device until
installation has been completed and the device is fully sealed and secured.
•To reduce the risk of ignition of hazardous atmospheres and shock, keep device tightly closed when the circuit is energised.
•Before removing the cover for installation or
maintenance, ensure that the power to the device is isolated.
•Following installation, test the device to ensure correct operation.
•Following installation ensure a copy of this manual is made available to all operating personnel
•When installing the device, requirements for selection, installation and operation should be referred to e.g. IEE Wiring Regulations and the ‘National Electrical
Code’ in North America. Additional national and/or local requirements may also apply.
•Cable termination should be in accordance with the specification applying to the required application.
MEDC recommends that all cables and cores should be correctly identified. Please refer to the wiring diagram in this manual (or separate diagram provided with the unit).
•Ensure that only the correct listed or certified cable glands are used and that the assembly is correctly earthed.
•Ensure that only the correct listed or certified stopping plugs are used to blank off unused gland entry points in accordance with EN/IEC60079-14 clauses 16.3, 16.4 & 16.5 and that the NEMA/IP rating of the unit is maintained.
•MEDC recommend the use of a sealing compound such as HYLOMAR PL32 on the threads of all glands and stopping plugs and/or a suitable sealing washer in order to maintain the IP rating of the unit.
•The internal earth terminal must be used for protective earthing when required. Do not remove the internal ground strap from the earth terminal where fitted.
•For units with metric entries; gland continuity and earthing may be achieved with an optional external earth plate. If the external plate is fitted, a thread sealing compound such as HYLOMAR PL32 must be employed to maintain the IP rating of the unit.
•When installing the device, MEDC recommends the use of stainless-steel fasteners. Ensure that all nuts, bolts and fixings are secure.
•The unit should never be positioned with the sunshield horizontal facing down.
•The purchaser should make the manufacturer aware of any external effects or Aggressive substances that the equipment may be exposed to.

Electrical installation and servicing should only be carried out by qualified service personnel and in accordance with all local/national codes of practice and standards e.g. EN 60079 - 14:2014 and IEC 60079 -14:2013.
Due to the large number of possible configurations, this manual only covers the standard installation of the units. For detailed connection and configuration of units, the installer should refer to individual project specific drawings and information.
Units can be supplied, as required, with either AC or DC 24V , or 220VAC Supply; all ±10% The units should only be powered from the specified voltage, no allowance is made for varying voltage supply. Units may also work with Power Over Ethernet (POE) 12V ,24v,48v & 56V DC
WARNING: IRREPARABLE DAMAGE TO THE UNIT
WILL RESULT FROM AN INCORRECT POWER SUPPL Y VOLTAGE
For safe access to electrical connections with the camera, refer to ATEX controlled certified ANNEX to this manual.

7.0 INSTALLATION
It is not anticipated that entry into the flame proof enclosure will be required by the user as power and transmission cables are supplied pre-installed with the unit. However, when opening the unit for any reason, follow the steps below.
WARNING: D O NOT OPEN WHEN ENERGISED OR
WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT . CLEAN WITH DAMP CLOTH 1. Cable termination should be in accordance with
specifications applying to the application.2. MEDC recommend that all cables and cores should
be fully identified.3. Ensure that only the correct certified glands are
used, and that the assembly is shrouded and correctly earthed 4. Ensure there is not too much slack of cable cores
within the unit, due to space limitations.
5. Ensure that only the correct certified stopping
plugs are used to blank any unused gland entry points. We recommend the use of ‘HYLOMAR PL32 COMPOUND’ on the threads of stopping plugs in order to maintain the IP66/67 rating of the unit.6. Unscrew the grub screw on the Lens cover
assembly one full turn (2.0mm A/F hexagon key required).7. Unscrew and remove the cover. Once the cover
has been removed, slide the camera from the enclosure.8. To replace the cover, use the same procedure as
above but in reverse manner, ensuring the cover is screwed tightly. There should be a maximum gap of 0.2mm between the faces of the enclosure and cover to ensure 0-ring compression.

erminals
Loosen the grub screw before attempting to unscrew the cover. See Note 6.
Slide the camera from the
enclosure. See Note 7.
WARNING: T HIS COVER MUST NOT BE REMOVED
UNDER ANY CIRCUMSTANCES, UNTIL AT LEAST 5 MINUTES AFTER THE POWER SOURCE IS DISCONNECTED.

Flame ProoF Camera – XFG1 TM400/B July 2022 8.0 MAINTENANCE
However, if abnormal and/or persistent unusual
environment conditions occur due to plant damage or accident etc, then a visual inspection is recommended.If the unit requires cleaning, then only clean with a damp cloth to avoid electro-static charge build up.
Recommended inspection interval: 6 Months to ensure trouble free operation and extended product life.
It is recommended that, where the unit is exposed to
regularly extreme weather conditions, the ‘O’ ring weather seal in the removable window is replaced every five years. If the cover/lens assembly grease needs to be re-applied, a PFPE (Perfluoropolyether) based grease such as Krytox GPL203 by DuPont or Perfluorolube 22/6 by Performance Fluids Ltd should be used, to prevent damage to the O-ring.
Fixings and fastenings should be checked for tightness and integrity as part of the 6 monthly inspection intervals. All cable entries and cables should be checked for integrity at these points also.
Extreme and harsh environments may require more frequent inspection and maintenance checks. Therefore, the end user or installer shall ensure that this equipment is protected against external influences which could adversely affect the explosion protection or contact the manufacturer if in doubt of the suitability of this equipment in the environment in which it is to be installed.
INSPECTON SUMMARY
At every Inspection interval, carry out the following:
•Clean the exterior of the unit.
•Check the ‘O’ ring weather seals and replace if necessary.
•Check the integrity of all cable entries and cables.
•Check condition & tightness o all fasteners on the unit and any mounting points.
•Use only Eaton approved spare parts.
