Cable termination should be in accordance with specifications applying to the re-

quired 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 strobe 

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 and the external terminal is for a supplementary bonding connection 

where local codes or authorities permit or require such a connection.

 

Once termination is complete replace the PCB assembly onto the mounting pillars and 

fully tighten the thumbscrews. Take care not to over tighten. Replace the cover assembly, 

ensuring the cover is screwed down fully. There should be a maximum gap of 

1

/

128

(0.2mm) between the faces of the cover and enclosure to ensure o-ring compression. 

Ensure the cover seal is correctly seated in its groove during re-assembly. Re-tighten 

the grub screw in the cover flange to secure the cover.

3.  OPERATION

 

The operating voltage of the unit is stated on the unit label.

 

The beacon can be powered directly or initiated by a 24Vdc relay if requested when 

ordered.
