2.2
Wiring
l
Be sure to ground the unit.
Otherwise, there is a danger of electric shock and/or fire.
l
Wiring work should be carried out by qualified electricians.
Otherwise, there is a danger of electric shock and/or fire.
l
Implement wiring after checking that the power supply is off.
Otherwise, there is a danger of electric shock and/of fire.
l
After mounting the inverter, carry out wiring.
Otherwise, there is a danger of electric shock and/or injury.
l
Do not remove the rubber bushings where wiring connections are made.
(5.5 to 22kW) Due to the possibility that a wire may be damaged, shorted
or may have a ground fault with the edge of the wiring cover.
l
Make sure that the input voltage is:
Three phase 200 to 240V 50/60Hz
(Model : N700E-055LF/075LFP~220LF)
Three phase 380 to 480V 50/60Hz
(Model : N700E-055HF/075HFP~3500HF/3800HFP)
l
Be sure not to power a three-phase-only inverter with single phase power.
Otherwise, there is a danger of fire.
l
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 and/or damage to unit.
l
Be sure not to connect a resistor to the DC terminals(PD, P) directly.
Otherwise, there is a danger of fire and/or damage to unit..
l
Be sure to set a earth leakage breaker or the fuse(s) which is(are) the same
phase as the main power supply in the operation circuit.
Otherwise, there is a danger of fire and/or damage to unit..
l
As for motor leads, earth leakage breakers, and electromagnetic contactors,
be sure to use equivalent ones with the specified capacity(rated).
Otherwise, there is a danger of fire and/or damage to unit..
l
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.
l
Fasten the screws to the specified torque. Check so that there is no loosening of
screws.
Otherwise, there is a danger of fire and/or damage to unit..
