NOTE
• When a communication option is installed to the FR-A800-E/FR-F800-E series inverter, use the earthing (grounding) cable
supplied with the inverter instead of the earth plate supplied with the communication option. (For details of the installation
method, refer to the Instruction Manual of the inverter.)
• Always attach the earth plate. However, in the case of a malfunction caused by noises due to external factors, removing the
earth plate may mitigate the noises, decreasing frequency of malfunctions. When removing the earth plate, take measures
to reduce electric potential difference in earthing (grounding) between the inverter and other devices.
