2.2 Wiring
• Be sure to ground the unit.
Otherwise, there is a danger of electric shock and/or fire.
• Wiring work shall be carried out by electrical experts.
Otherwise, there is a danger of electric shock and/or fire.
• Implement wiring after checking that the power supply is off.
It might incur electric shock and/or fire.
• After installing the main body, carry out wiring.
Otherwise, there is a danger of electric shock and/or injury.
• Do not remove the rubber bush. (11 to 75kW)
Due to the possibility that a wire may be damaged, shorted or may have a ground fault with the edge
of the wiring cover.
• Make sure that the input voltage is:
Three phase 200 to 240V 50/60Hz (for models with suffix L)
Three phase 380 to 480V 50/60Hz (for models with suffix H)
• Be sure not to input a single phase.
Otherwise, there is a danger of fire.
• Be sure not to connect AC power supply to the output terminals(U, V, W).
Otherwise, there is a danger of injury and/or fire.
• Be sure not to connect the resistor to DC terminals (PD,P and N) directly.
Otherwise, there is a danger of fire.
• Be sure to set the earth leakage breaker or the fuse(s) (the same phase as the main power supply) in the
operation circuit.
Otherwise, there is a danger of fire.
• As for motor leads, earth leakage breakers and electromagnetic contactors, be sure to use the
equivalent ones with the specified capacity (rated).
Otherwise, there is a danger of fire.
• Do not stop operation by switching off the electromagnetic contactors on the primary or secondary sides
of the inverter.
Otherwise, there is a danger of injury and/or machine breakage.
• Fasten the screws with the specified fastening torque. Check so that there is no loosening of screws.
Otherwise, there is a danger of fire.
