Connect a Fuse to the Input Side (Primary Side)
The drive circuit protection must comply with IEC/EN 61800-5-1:2007 for protection against a short circuit in the
internal circuitry. Yaskawa recommends connecting semiconductor protection fuses on the input side for branch
circuit protection.
WARNING
Electrical Shock Hazard. After the drive blows a fuse or trips a GFCI, 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.
