D.3 UL and CSA 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.
Figure D.6
This drive is tested in accordance with UL standard UL508C and complies with UL requirements. To ensure continued
compliance when using this drive in combination with other equipment, meet the following conditions:
■
Installation Area
Do not install the drive to an area greater than pollution severity degree 2 (UL standard).
■
Main Circuit Terminal Wiring
Yaskawa recommends using closed-loop crimp terminals on all drive models. UL/cUL approval requires the use of
closed-loop crimp terminals when wiring the drive main circuit terminals on models CIMR-L 2A0085 to 2A0415 and
4A0045 to 4A0260. Use only the tools recommended by the terminal manufacturer for crimping.
