Installation and Maintenance Instructions
• G-LED 24VDC
• G-LED 120-240VAC
Ex d units are supplied with a six position PCB mounted screw terminal block.
The maximum wire gauge is 4 mm
higher. Use only stranded cable to terminate the beacon. The cross-sectional
area of the primary earth (ground) must equal the cross-sectional area of the
phase conductor.
Cable termination for these models should be in accordance with specifications
applying to the application. It is recommended that all cables and cores should
be fully identified. Use the appropriate cable gland for the application. Gland
entry threads are M20-1.5 x 6H.

Tools needed:

• 1.5 mm A/F hexagon key
• 2 mm flat-tip screwdriver
• No. 1 Phillips screwdriver
• Wire stripper

Wiring the Ex d Models

To wire the Ex flameproof beacon:
1.
Unscrew the M3 hex set screw on the side of the housing one
full turn.
2.
Remove the lens cover from the housing by turning the cover counter-
clockwise. Three 120-degree spaced reliefs are provided for a 3/8 in
spanner wrench if needed. If the cover will not unscrew, back out the
set screw a few additional turns.
3.
Loosen the captive Phillips screw retaining the printed circuit board
(PCB).
4.
Slide out the PCB until the terminals clear the housing. Strip the wire
insulation 8 mm (0.31 in). Maximum screw tightening torque is 0.6 Nm
(5 in-lb).
