Input/Output Signal Line Cautions
•
All FP 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.
The FP unit's backlight is user replacable.
For an explanation of how to replace the FP unit's backlight, please refer to
the backlight's Installation Guide.
Corresponding Replacement Backlight

Use a grounding resistance of 100
Ω
, a wire of 2mm

Please pay special attention to the following instructions when connecting
the power cord terminals to the FP unit.
•
If the power supply voltage exceeds the FP unit's specified range, connect
a voltage transformer.
•
Between the line and the ground, be sure to use a low noise power supply.
If there is still an excessive amount of noise, connect a noise reducing
transformer.
•
Input and Output signal lines must be separated from the power control
cables for operational circuits.
•
The FP unit's power supply cord should not be bundled with or kept close to
main circuit lines (high voltage, high current), or input/output signal lines.
•
Connect a surge absorber to handle power surges.
•
To reduce noise, make the power cord as short as possible.
