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:
n
Installation Area
Do not install the drive to an area greater than pollution degree 2 (UL standard).
n Ambient Temperature
IP00/Open Type Enclosure: -10 °C to +50 °C (14 °F to 122 °F)
IP20/UL Type 1 Enclosure: -10 to +40 °C (14 °F to 104 °F)
Finless Type: IP20/IP00 Enclosure: -10 to +45 °C (14 °F to 113 °F)
n 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 5A0041 to
5A0242. Use only the tools recommended by the terminal manufacturer for crimping.
Recommendations on page 355
Note: The mark indicates the terminals for protective ground connection as defined in IEC/EN 60417-5019.
Grounding impedance: 600 V: 10 Ω or less
