C.1 UL Standards
UL Standards Compliance
The UL/cUL mark applies to products in the United States and Canada. It indicates that UL has performed product testing
and evaluation, and determined that their stringent standards for product safety have been met. For a product to receive
UL certification, all components inside that product must also receive UL certification.

This drive is tested in accordance with UL standard UL508C and complies with UL requirements. The conditions
described below must be met to maintain compliance when using this drive in combination with other equipment:
Installation Area
Do not install the drive to an area greater than pollution degree 2 (UL standard).
Ambient Temperature
Install the drive in an environment with an ambient temperature of -10°C to 40°C (Flange Type Enclosure).
Factory Recommended Branch Circuit Protection
Yaskawa recommends installing one of the following types of branch circuit protection on a secondary circuit of a 6-
Phase/12-Pulse transformer to maintain standards compliance.
Refer to local codes for proper Branch Circuit Protection on the primary circuit of a 6-Phase/12-Pulse transformer.
The maximum Time Delay fuse is 175% of drive input current rating listed in Table C.1. This covers any Class CC, J or T
class fuse.
A Class L fuse is also approved for this rating at 175% drive input current listed in Table C .1.
