1) Product Table
Ensure the system power supply is capable of providing the maximum current required for all beacons. Review associated cable
size, length and quantity of beacons on each circuit.
2) Warnings

POTENTIAL ELECTROSTATIC CHARGING HAZARD

DO NOT OPEN WHEN AN EXPLOSIVE
ATMOSPHERE IS PRESENT

ALL ENTRIES M20 X 1.5

IF TEMPERATURE EXCEEDS 70ºC AT ENTRY OR 80ºC
AT BRANCHING POINT USE SUITABLE RATED CABLE
AND CABLE GLANDS
3) Marking & Rating Information
All units have a rating label, which carries the following
important information:-

Unit Model.

Voltage Range

Nominal Voltage

