*1. Select a Noise Filter in accordance with the amount of the leakage current. If there is no problem with the
amount of the leakage current, you can select the R88A-FI1S202.
• If the molded case circuit breaker is located in an upper area and the power supply is wired through
the duct at the bottom, keep a sufficient distance between the input wires and internal wires, or use
the metal tubing for wiring. If input and output cables are placed in the same duct, the noise immunity
will be impaired.
• Place the noise filter as close as possible to the opening of the control panel. Use the diagram below
to the left for wiring.
