Inverter and peripheral devices
1.2.1

Peripheral devices

Check the inverter type of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices:

∗1
Select an MCCB according to the power supply capacity.
Install one MCCB per inverter.
∗2
For installations in the United States or Canada, use the class T type fuse certified by the UL and cUL.
∗3
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 stop during motor driving, the electrical durability is 25 times.
When using the MC for emergency stop during motor driving or using on the motor side during commercial-power supply operation, select the MC with class
AC-3 rated current for the motor rated current.
∗4
The power factor may be slightly lower.
NOTE
When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to
the inverter type and cable and reactor according to the motor output.
When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts
of the inverter, etc. Identify the cause of the trip, then remove the cause and power on the breaker.
