NOTE
• The matrix shows the magnetic contactor selected according to the standards of Japan Electrical Manufacturers' Association
(JEM standards) for AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor
is used for emergency stops during motor driving, the electrical durability is 25 times. If using an MC for emergency stop during
motor driving, select an MC for the inverter input current according to the rated current against JEM 1038 standards for AC-3
class. When installing an MC at the inverter output line to switch to the commercial-power supply operation while running a
general-purpose motor, select an MC for the rated motor current according to the rated current against JEM 1038 standards
for AC-3 class.
• When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the
inverter model, and select cables and reactors according to the motor output.
• When the breaker on the inverter's input side trips, check for the wiring fault (short circuit), damage to internal parts of the
inverter etc. The cause of the output shutoff must be identified and removed before turning ON the power of the breaker.
