Preparing to Wire the Ex de Increased Safety Models

SHOCK HAZARD: To avoid electrical shock hazards, do not connect wires
when power is applied. Failure to observe this warning may lead to serious
injury or death.
This section has wiring instructions for the two increased safety models:
G-LED 24VDC
G-LED 120-240VAC
Ex de units are supplied with a six-pole spring tension clamp style terminal
block. The maximum wire gauge is 4.0 mm
85 °C or 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 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 6H.
Conductive metalwork, including cable glands, must be a minimum of 5 mm
away from the terminals.
Leads connected to the terminals shall be insulated for the appropriate voltage
and this insulation shall extend to within 1 mm of the metal of the terminal
throat.
The G-LED terminal block is supplied with two conductors per pole. The
terminal block allows for easy supply-in and loop-out wiring to connect beacons
in series.
Tools needed:
• 3.0 mm hexagon key
• No. 1 Phillips screwdriver
• Wire stripper

Wiring the Ex de Models

CIRCUIT BOARD DAMAGE: The DC beacons are polarity sensitive, and
MAY BE DAMAGED by incorrect electrical hookup. When connecting
the DC beacon to the voltage supply lines, POLARITY MUST BE
OBSERVED. In addition, damage will result if the voltage rating of the
particular model is exceeded by more than 10 percent.
