
The magnetic contactor is selected based on the 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 driving the motor, select an MC regarding the converter unit input side current as JEM 1038-AC-3
class rated current. When using an MC on the inverter output side for commercial-power supply operation switching using a general-purpose
motor, select an MC regarding the rated motor current as JEM 1038-AC-3 class rated current.
NOTE
• When the breaker on the converter unit's input side trips, check for the wiring fault (short circuit), damage to internal parts of
the inverter and the converter unit, etc. The cause of the trip must be identified and removed before turning ON the power of
the breaker.
