3.15 Protect the Drive during Failures
◆ Factory-Recommended Branch Circuit Protection for UL Listing
Use branch circuit protection to protect against short circuits and to maintain compliance with UL 508C. Yaskawa
recommends connecting semiconductor protection fuses on the input side for branch circuit protection. Refer to
Three-Phase 200 V Class on page 125 and Three-Phase 400 V Class on page 126 for more information about
recommended fuses.
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.
• 200 V Class
Use the fuses specified in this document to prepare the drive for use on a circuit that supplies not more than
100,000 RMS and not more than 240 Vac when there is a short circuit in the power supply.
• 400 V Class
Use the fuses specified in this document to prepare the drive for use on a circuit that supplies not more than
100,000 RMS and not more than 480 Vac when there is a short circuit in the power supply.
The built-in short circuit protection of the drive does not provide branch circuit protection. The user must provide
branch circuit protection as specified by the National Electric Code (NEC), the Canadian Electric Code, Part I
(CEC), and local codes.
