Ensure that only the correct listed or certified cable glands are used and that the assembly is shrouded and cor-
rectly earthed.
All cable glands should be of an equivalent NEMA/IP rating to that of the beacon and integrated with the unit
such that this rating is maintained.
The internal earth terminal, where fitted, must be used for the equipment grounding connection.
Once termination is complete, carefully replace the cover assembly back onto the base, avoiding damage to the
mating surfaces. Replace the 6 off M5 screws (4.0mm A/F hexagon key) into the holes in the cover assembly
and tighten evenly. Ensure the O-ring is seated correctly on the cover during re-assembly. Ensure the required
maximum gap of 0.2mm is maintained between the cover and the base once assembled.

4.0 MAINTENANCE
During the working life of the unit, it should require little or no maintenance. GRP will resist attack by most acids,
alkalis and chemicals and is as resistant to concentrated acids and alkalis as most metal products.
However, if abnormal or unusual environmental conditions occur due to plant damage or accident etc., then visual
inspection is recommended.
If the unit requires cleaning, then only clean exterior with a damp cloth to avoid electro-static charge build up.
Replacement of the filament bulb (see below) can be carried out by competent site personnel. Other repairs should
be undertaken by returning the unit to MEDC or by an authorised repairer of Ex equipment.
If a unit fault should occur, then the unit can be repaired by MEDC. All parts of the unit are replaceable.
If you acquired a significant quantity of units, then it is recommended that spares are also made available. Please
discuss your requirements with the Technical Sales Engineers at MEDC.
Removing / replacing filament bulb
CAUTION: Before removing the cover assembly, ensure that the power to the unit is isolated.
Unscrew and remove the 6 off M5 (4.0mm A/F hexagon key). Keep in a safe, accessible location as they are
non-captive
Twist the cover assembly gently clockwise and anti-clockwise, whilst pulling it away from the base. Remove to
gain access to the interior.
