Component Name Installation Position Function Description
Circuit breaker Between the power supply and
input side of the power supply
unit
MCCB: Cuts off power supply when overcurrent occurs on
downstream devices.
Earth leakage circuit breaker: Provides protection against
potential leakage current during drive running to prevent
electric shock and even a fire.
Fuse Between the power supply and
input side of the power supply
unit
Protects downstream semiconductors of the power supply
unit in case of short circuits.
Electromagnetic
contactor
Between the circuit breaker and
input side of the power supply
unit
Switches ON/OFF the drive. Do not start/stop the drive
frequently using the contactor (keep an interval of at least 1
hour between ON and OFF operations) or use it to directly
start the drive.
