◆ Factory-Recommended Branch Circuit Protection for UL Listing
Yaskawa recommends that you install one of these types of branch circuit protection to comply with UL 508C.
Semiconductor protective type fuses are recommended, but the tables also show alternative branch circuit protection
devices. Maximum Time Delay fuse is 175% of drive full load output amps (FLA). This includes all Class CC, J, or T
class fuses. Refer to Table 12.2 to Table 12.3 for the recommended fuses.
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.
• 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 user must provide branch circuit protection to protect input branch circuits as specified by the National Electric
Code (NEC), the Canadian Electric Code, Part I (CEC), and local codes.
