D.3 UL Standards
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.

◆ UL Standards Compliance
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 severity 2 (UL standard).

Main Circuit Terminal Wiring
Cable Connectors
Yaskawa recommends using UL-listed copper wires (rated at 75°C), and closed-loop connectors or CSA-certified ring
connectors sized for the selected wire gauge to maintain proper clearances when wiring the drive. Use the correct crimp
tool to install connectors per manufacturer recommendation. Table D.3 lists a suitable closed-loop connector
manufactured by JST Corporation.
