•
To prevent the Ring Terminals
*1
from short-circuiting when the terminal
block attachment screws are loosened, use sleeve-type Ring Terminals.
•
When the FG terminal is connected, be sure that the wire is grounded.
Not grounding the GLC unit will result in excessive noise. Use your
country’s applicable standard for grounding.
•
The SG and FG terminals are conneted internally in the GLC unit.
•
When connecting the SG line to another device, be sure that the design
of the system/connection does not produce a shorting loop.
•
Whenever possible, use thick wires (max. 2mm
2
) for power
lines, and twist the exposed wire ends when connecting
the Ring Terminals.
•
Use the following crimp-on type Ring Terminals.
•
To avoid an electric shock, be sure the power cord is un-
plugged from the power outlet when connecting the power
terminals to the GLC unit.
•
The GLC2400-TC41-24V, GLC2500-TC41-24V and GLC2600-
TC41-24V units are designed to use only DC24V input. Any
other power level can damage both the GLC and the power
supply.
•
The GLC2500-TC41-200V and GLC2600-TC41-200V units are
designed to use only with 100 V to 240V AC input. Any other
power level can damage both the GLC and the power sup-
ply.
•
The GLC is not equipped with a power switch. Therefore,
be sure to connect a breaker type power switch to the GLC
unit’s power cord.
•
The FG terminal must be connected to earth, to protect
against electrical shock when the unit breaks down.
