Peripheral devices
(1) Selection of peripheral devices
Check the capacity of the motor to be used with 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) 200V class
must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices:
1) 200V class
2) 400V class
Note: 1. Select the NFB according to the inverter capacity (motor capacity.)
For installations in the United States or Canada, the circuit breaker must be inverse time or
instantaneous trip type.
When the breaker on the primary side of the inverter tripped, check for wiring fault (e.g. short
circuit), damage to internal parts of the inverter, etc. Identify the cause of the breaker trip, then
power on the breaker after removing the cause of the trip.
2. Select the electromagnetic switch in parenthesis when using it for emergency stop while driving a
motor.
