• When attaching a wire to the GP's rear face FG terminal, (on the Power Input
Terminal Block), be sure to create an exclusive ground.

• Inside the GP2301H-LG41-24V/GP2301H-SC41-24V/GP2401H-TC41-24V unit,
the SG(Signal Ground) and FG(Frame Ground) terminals are connected.
• When connecting the SG line to another device, be sure that the design of the
system/connection does not produce a shorting loop.
Please pay special attention to the following instructions when connecting the power
cord terminals to the GP unit.
•
Between the line and the ground, be sure to use a low noise power supply.
•
Input and Output signal lines must be separated from the power control cables
for operational circuits.
•
To increase the noise resistance, be sure to twist the ends of the power cord
wires before connecting it to the GP unit.
•
Connect a surge absorber to handle power surges.
•
To reduce noise, make the power cord as short as possible.
*1
Use a grounding resistance of 100
Ω
, a wire of 2mm
2
or thicker, or your country's applicable
standard.
•
All GP Input and Output signal lines must be separated from all operating circuit
(power) cables.
•
If this is not possible, use a shielded cable and ground the shield.
