GP-477R/577R Series User's Manual 3-5

When the FG terminal is connected, be sure the wire is grounded. Not

grounding the GP unit will result in excess noise.

• Wherever possible, use thick wires (max 2mm

) for power terminals, and twist the

exposed wire ends when connecting the Ring Terminals.

• Please use the following sized Ring Terminals.

• To prevent the Ring Terminals from causing a short when the terminal block

attachment screws are loosened, be sure to use sleeve-type Ring Terminals.

• Do not wire the cable either near or parallel to high voltage or high current power

lines.

Note:

3.2 Wiring Cautions

1. Connecting the GP's Power Cable

over Ø3.2mm

under Ø6.0mm

• To avoid an electric shock, be sure the GP’s power

cord is unplugged from the main power outlet

when connecting the power cord terminals to the

GP unit.

• The GP477R-EG41-24VP and GP577R-TC41-24VP

panels accept DC 24V power only. Using an incor-

rect power supply can damage both the power

supply and the GP.

• Be sure to connect a breaker type power switch to

the GP’s power cord.

• When connecting the power cord power terminals

to the GP, be sure to ground the FG (

) terminal,

since there is possibility of an electric shock if the

GP malfunctions.
