Wiring Precautions
• Signal lines and power lines must be separated to avoid influence of noise.
• Do not lay cables close to antennas.
• Wiring must be done while power is off.
• Use a pin terminal or a cable for connection as shown below.
A pin terminal must be clamped with an appropriate tool based on its size.The tip of a wire must be cut in the
same length as the pin terminal or 0.5mm longer.A whisker must not exist, and a pin terminal must not be
broken.
• Plug the pin terminal into the power terminal block to the end.Fix wiring close to its connector so that a
cable should not apply load to the connector due to its twisting or weight.
• A pin terminal must be unplugged while inserting a flat-head screw driver as shown below.
