3. Installation and Wiring
3-14
②
Never connect the phase advancing capacitor to the inverter output. If already
installed, remove the phase advancing capacitor clearly.
③
Cable between inverter output and motor should be less than 30m long. If cable gets
long, surge voltage appears across motor terminals depending on the cable
parameters. Especially, in 400V class motor case, insulation withstanding voltage
may be decreased. Use an insulation-enforced motor when 400V class motor is used.
Distance between
inverter and motor
Up to 50m
Up to 100m Over 100m
Permitted Carrier Frequency
Below
10kHz
Below 5kHz
Below
2.5kHz
(In case of below 3.7 kW, use the cable of output within 100 m)
④
Crimp terminal with insulation cap should be used for the input power supply and
the motor.
⑤
After finishing wiring, be certain to remove all the wire or cable scraps inside
the inverter.
⑥
Use the shield cable or twist-paired wire for control circuit terminal. Do not put
them into the same wiring duct for the power terminal.
⑦
When wiring is changed after operating the inverter, be sure to check LCD
window on the keypad or charge lamp is turned off. Capacitors inside inverter
are charged with high voltage and it may result in lethal injury.
⑧
Below 22kW inverter, B1 and B2 on the power terminal should not be connected
to anything else other than DB resistors.
