2.23 Protect the Drive during Failures
◆
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
to
for the recommended fuses.
•
200 V Class
This product complies with UL under the conditions for use on a circuit capable of delivering not more than
100,000 RMS symmetrical Amperes and 240 Vac maximum during a short circuit of the power supply, when
protected by fuses as specified in this document.
•
400 V Class
This product complies with UL under the conditions for use on a circuit capable of delivering not more than
100,000 RMS symmetrical Amperes and 480 Vac maximum during a short circuit of the power supply, when
protected by fuses as specified in this document.
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.
