CAUTION
1. Do not plug the connector to a computer LAN board, fax modem socket,
telephone modular connector etc. as they are different in electrical specifications,
the inverter may be damaged.
2. Pins 2 and 8 (P5S) are provided for the parameter unit power supply. Do not use
them for any other purpose or when making parallel connection by RS-485
communication.
(1) When connecting the parameter unit
Use the optional FR-CB2 .
