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 UL/cUL Mark
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:
n
Installation Area
Do not install the drive to an area greater than pollution degree 2 (UL standard).

Main Circuit Terminal Wiring
Yaskawa recommends using closed-loop crimp terminals on all drive models. To maintain UL/cUL approval, UL Listed
closed-loop crimp terminals are specifically required when wiring the drive main circuit terminals on models 2A0110 to
2A0415, 4A0058 to 4A1200, and 5A0041 to 5A0242. Use only the tools recommended by the terminal manufacturer for
crimping. Refer to Closed-Loop Crimp Terminal Size on page 558 for closed-loop crimp terminal recommendations.
The wire gauges listed in the following tables are Yaskawa recommendations. Refer to local codes for proper wire gauge
selections.
Note:
The mark indicates the terminals for protective ground connection as defined in IEC60417-5019.
Grounding impedance:
200 V: 100 Ω or less
400 V: 10 Ω or less
600 V: 10 Ω or less
