For ease of installation the beacon lens is supplied loose from the mounting back box. The back box must be mounted with the two cable entries either at the top or the bottom. The back box should be mounted to a suitable flat wall, bulkhead or conduit box avoiding areas of undue vibration and using the internal fixing point options in the back box. Always use the mounting gasket supplied. 

The recommended fixing screws are 4.5mm Dia x 20mm Long. 

To maintain the IP rating of the enclosure the cable entries must be fitted with a suitably rated cable gland  (Not Supplied). Max cable termination 2.5mm ².
