SAFETY PRECAUTIONS
2.Wiring
• Be sure to ground the unit.
Otherwise, there is a danger of electric shock and/or fire.
……
p.2-9
• Wiring work shall be carried out by electrical experts.
Otherwise, there is a danger of electric shock and/or fire.
……
p.2-6
• Implement wiring after checking that the power supply is off.
It might incur electric shock and/or fire.
……
p.2-8
• After installing the main body, carry out wiring.
Otherwise, there is a danger of electric shock and/or injury.
……
p.2-5
• 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.
……
p.2-4
• 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)
……
p.2-6
• Be sure not to input a single phase.
Otherwise, there is a danger of fire.
……
p.2-8
• 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.
……
p.2-5
• Be sure not to connect the resistor to DC terminals (PD,P and N) directly.
Otherwise, there is a danger of fire.
……
p.2-5
• 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.
……
p.2-12
• 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.
……
p.2-12
• 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.
……
p.2-6
• Fasten the screws with the specified fastening torque. Check so that there
is no loosening of screws.
Otherwise, there is a danger of fire.
