The drive circuit protection must comply with IEC/EN 61800-5-1 for protection against a short circuit in the internal circuitry. Yaskawa recommends that you install semiconductor protection fuses or ELCBs on the input side for branch circuit protection.

Electrical Shock Hazard
After the drive blows a fuse or trips an ELCB, do not immediately energize the drive or operate peripheral devices. Wait for the time specified on the warning label at a minimum and make sure that all indicators are OFF. Then check the wiring and peripheral device ratings to find the cause of the problem. If you do not know the cause of the problem, contact Yaskawa before you energize the drive or peripheral devices.
If you do not fix the problem before you operate the drive or peripheral devices, it can cause serious injury or death.
