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:
■ Conditions of Acceptability
• With respect to models CIMR-U  4  0720 to 4  0930, a harmonic filter module shall be installed on the input of the
drive (see Table D.2 and Table D.3 ).

■ Main Circuit Terminal Wiring
Yaskawa recommends using closed-loop crimp terminals on all drive models. Use only the tools recommended by the
terminal manufacturer for crimping.
The wire gauges listed in Table D.4 to Table D.7 are Yaskawa recommendations. Refer to local codes for proper wire
gauge selections.
Note: The mark indicates the terminals for protective ground connection.
