To avoid the possibility of an electric shock, be sure the Power Cord is unplugged
from the power outlet prior to connecting the power cord's power terminals to the
GLC.

The GLC300-TC41-24V can only use  DC24V input.  Any other input voltage can
damage the GLC and its power supply.

Since the GLC has no power switch, be sure to use a breaker type switch.

 To prevent a short from occurring when the ring terminals

   become loose, be sure to use sleeved ring terminals.

 

 

When the FG terminal is connected, be sure the wire is

grounded.  Not grounding the GLC unit will result in excess
noise and vibration.

• 

 Wherever possible, use thick wires (max. 2 mm

2

) for power

   terminals, and twist the wire ends before attaching the ring terminals.

  Be sure to use the following size Ring Terminals.
