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

Unscrew the set screw in the flange of the cover 3 turns minimum (2.0mm A/F hexagon key). Unscrew

and remove the cover and lens assembly using the spanner supplied to gain acess to the inside of the

unit. Unscrew the 2 off thumbscrews and carefull lift the PCB assembly clear of the mounting pillars to

gain access to the terminals.

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 in this manual or supplied with the product if specific qiring has been specified.

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

and correctly earthed. For supply connections, use minimum 90°C rated wire.

WIRING DETAIL

All cable glands should be of an equivalent NEMA/IP rating to that of the unit 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 PCB assembly onto the mounting pillars and fully

tighten the thumbscrews. Take care not to over tighten. Replace the cover and lens assembly, ensuring the

cover is screwed down fully and that the cover seal is correctly seated during re-assembly. There should

be a maximum gap of 1/128” (0.2mm) between the faces of the cover and enclosure to ensure correct

o-ring compression. Re-tighten the set screw (2.0mm A/F hexagon key) in the cover flange to secure the

cover into position.
