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.
