Factory-Recommended Branch Circuit Protection

Use branch circuit protection to protect against short circuits and to maintain compliance with UL61800-5-1.
Yaskawa recommends connecting semiconductor protection fuses on the input side for branch circuit protection.
Refer to Table 2.30 to Table 2.33
WARNING! Electrical Shock Hazard. Do not immediately energize the drive or operate peripheral devices after the drive blows
a fuse or trips an RCM/RCD. 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. Contact Yaskawa before energizing
the drive or peripheral devices if the cause is not known. Failure to obey can cause death or serious injury and damage to the
drive.
• 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 symmetrical amperes and 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 symmetrical amperes and 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.
