Wiring
• To avoid an electric shock, prior to connecting the GLC's power cord
terminals to the power terminal block, confirm that the GLC's power
supply is completely turned OFF, via a breaker, or similar unit.
• The GLC2300-LG41-24V/GLC2300-TC41-24V units are designed
to use only DC24V input. Any other power level can damage both
the GLC and the power supply.
• Since there is no power switch on the GLC unit, be sure to attach
a breaker type switch to its power cord.
• When the FG terminal is connected, be sure the wire is grounded.
• To avoid a short caused by loose ring terminals, be sure to use ring
terminals with an insulating sleeve.
• When the FG terminal is connected, be sure the wire is grounded. Not
grounding the GLC unit will result in excess noise and vibration.
• The SG and FG terminals are connected internally in the GLC unit.
• When connecting the SG line to another device, be sure that the de-
sign of the system/connection does not produce a shorting loop.
• Wherever possible, use thick wires (max. 2 mm
twist the wire ends before attaching the ring terminals.
• Be sure to use the following size ring terminals.
