5.2 European Standards

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 an RCM/RCD, 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.

CE Standards Compliance for DC Power Supply Input

To comply with CE Standards, install a fuse for the DC power supply input.
