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
IP20/NEMA 1, UL Type 1 Enclosure, External Heatsink (2A0011 to 2A0073 and 4A0005 to 4A0302): -10 to +40 °C (14 to
104 °F)
IP00/Open Type Enclosure (2A0343 and 2A0396 and 4A0361 to 4A0590): -10 to +50 °C (14 to 122 °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 2A0031 to
2A0396 and 4A0034 to 4A0590. Use only the tools recommended by the terminal manufacturer for crimping.
Loop Crimp Terminal Size on page 372
The wire gauges listed in the following tables are Yaskawa recommendations. Refer to NEC table 310-16 for proper wire
gauge selection for terminals -M, +M, -1, +3, and ground.

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 2A0031 to
2A0396 and 4A0034 to 4A0590. Use only the tools recommended by the terminal manufacturer for crimping. Yaskawa
recommends crimp terminals made by JST and Tokyo DIP (or equivalent) for the insulation cap.
Table D.3 matches the wire gauges and terminal screw sizes with Yaskawa-recommended crimp terminals, tools, and insulation
caps. Refer to the appropriate Wire Gauge and Torque Specifications table for the wire gauge and screw size for your drive
model. Place orders with a Yaskawa representative or the Yaskawa sales department. Refer to local codes for proper selections.
