7 Power Supply Cautions
„ „ „ „ „Power Supply Cautions
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.
„ „ „ „ „Grounding Cautions
• When attaching a wire to the FP unit's rear face FG terminal, (on the AC
Connector), be sure to create an exclusive ground.
