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 i.16 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).
n
Ambient Temperature
IP20/NEMA Type 1 Enclosure: -10 to +40 °C
IP00 Open Type Enclosure: -10 to +50 °C

Closed-Loop Crimp Terminal Recommendations
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.
Refer to Closed-Loop Crimp Terminal
for closed-loop crimp terminal recommendations.
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
.
Factory Recommended Branch Circuit Protection for UL Compliance
NOTICE: If a fuse is blown or a Ground Fault Circuit Interrupter (GFCI) is tripped, check the wiring and the selection of the peripheral devices.
Check the wiring and the selection of peripheral devices to identify the cause. Contact Yaskawa before restarting the drive or the peripheral
devices if the cause cannot be identified.
Yaskawa recommends installing one of the following types of branch circuit protection to maintain compliance with UL508C.
