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.

Three-Phase 200 V Class

Table 5.2 Factory-Recommended Branch Circuit Protection (200 V Class)

Yaskawa recommends a fuse with a large rated current for applications with repeated loads.

Three-Phase 400 V Class

Table 5.3 Factory-Recommended Branch Circuit Protection (400 V Class)

Yaskawa recommends a fuse with a large rated current for applications with repeated loads.
