Wiring The Ex De Models - Federal Signal Global G-STR Instrucciones De Instalación Y Mantenimiento

This section has wiring instructions for the three increased safety models:
• G-STR 24 Vdc
• G-STR 120 Vac
• G-STR 220-240 Vac
Ex de units are supplied with a six-pole, spring tension-clamp style terminal block.
The maximum wire gauge is 4.0 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 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-STR 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 A/F hexagon key
• No. 1 Phillips screwdriver
• Wire stripper

Wiring the Ex de Models

CIRCUIT BOARD DAMAGE: The DC units are polarity sensitive, and MAY
BE DAMAGED by incorrect electrical hookup. When connecting the DC
strobe unit 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.
To wire the Ex de beacon:
1.
Unscrew the four M4 socket-head cap screws and remove the terminal box
cover.
2.
Strip the wire insulation 8 mm to 9 mm (0.33 in).
