    INSTALLATION AND WIRING 2.1 Pre-Installation Instructions Make sure that the input power of the inverter is off. CAUTION With input power on, do not install or remove the plug-in option. Otherwise, the inverter and plug-in option may be damaged.

  • Page 11: Installation Procedure

    INSTALLATION AND WIRING 2.2 Installation Procedure 1) Remove the inverter front cover. 2) Mount the hex-head screw for option mounting into the inverter screw hole (on earth plate). (size 5.5mm, tightening torque 0.56N m to 0.75N m) 3) Securely fit the connector of the plug-in option to the inverter connector along the guides.

    INSTALLATION AND WIRING 2.3 Wiring (1) Strip off the sheath of the cable to wire. Strip off the sheath about the size below. If the length of the sheath pealed is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off. Wire the stripped cable after twisting it to prevent it from becoming loose.

    INSTALLATION AND WIRING (3) For wiring of the 30K(00620 (EC Version)) or less, route wires between the control circuit terminal block and front cover. If cables can not be routed between the control circuit terminal block and front cover due to the increased number of cables, remove a hook of the front cover and use a space become available.
