YASKAWA SIEPC71061753C GA500 Technical Manual 197
*2 If you turn on the internal EMC filter, the leakage current of the drive will be more than 3.5 mA. Use the closed-loop crimp terminals
to connect a protective ground wire that has a minimum cross-sectional area of 10 mm
2
(copper wire).
■ Factory-Recommended Branch Circuit Protection for UL Listing
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 Single-Phase 200 V Class on page 197, Three-Phase 200 V Class on page 197, and Three-Phase 400 V
Class on page 198for more information.
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
31,000 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
31,000 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.
