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 three increased safety models:
• G-STR 24 Vdc
• G-STR 120 Vac
• G-STR 220-240 Vac
The maximum wire gauge is 4.0 mm
rated 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-STR terminal block is supplied with three poles and two
conductors per pole. The terminal block allows for easy supply-in and
loop-out wiring to connect beacons in series.
