Listing
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.

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 fuses for semiconductor protection. Refer to
Class on page 148, and 6-Phase/12-Pulse 400 V Class on page 149
short circuit protection devices.

• 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 (NEC), the Canadian Electric Code, Part I (CEC), and
local codes.
