MEDC FL12 User Manual

Cable termination should be in accordance with specifications applying to the required application.
MEDC recommends that all cables and cores should be correctly identified. Please refer to the wiring diagram

provided with the product.
Ensure that only the correct listed or certified cable glands are used and that the assembly is shrouded and

correctly 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.
Once termination is complete, carefully replace the cover assembly back onto the base, avoiding damage to the

mating surfaces. Replace the 6 off M8 screws (6.0mm 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.

3.0 OPERATION
The operating voltage of the unit is stated on the unit label. The unit can be powered directly only.

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 fluorescent tubes (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 fluorescent tube

CAUTION: Before removing the cover assembly, ensure that the power to the unit is isolated.

Note: These units each contain up to three separate fluorescent tubes (depending on unit ordered). On units

with multiple tubes it is advised that all tubes should be replaced at the same time.
Unscrew and remove the 6 off M8 (6.0mm A/F hexagon key). Keep in a safe, accessible location as they are

non-captive
