„ 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. To ensure continued
compliance when using this drive in combination with other equipment, meet the following conditions:
Installation Area
Do not install the drive to an area greater than pollution severity degree 2 (UL standard).
Ambient Temperature
IP00 enclosure with top protective cover: -10 to +40 °C
IP00 enclosure: -10 to +50 °C
Main Circuit Terminal Wiring
• Refer to Wire Gauges and Tightening Torque on page 17 for terminal tightening torque and selecting wire gauge.
Refer to local codes for proper wire gauge selections.
• Refer to Closed-Loop Crimp Terminal Recommendations on page 24 for selecting closed-loop crimp terminals.
Yaskawa recommends using closed-loop crimp terminals on all drive models. UL/cUL approval requires the use of UL
Listed closed-loop crimp terminals when wiring the drive main circuit terminals on models 2A0106 to 2A0432 and
4A0056 to 4A0260. Use only the tools recommended by the terminal manufacturer for crimping.
Note: Use crimp insulated terminals or insulated tubing for wiring these connections. Wires should have a continuous maximum
allowable temperature of 75 °C 600 V UL approved vinyl sheathed insulation. Ambient temperature should not exceed 40°C.
Branch Circuit Protection Devices and Drive Short Circuit Rating
Yaskawa recommends installing one of the following types of branch circuit protection to maintain compliance with
UL508C.Semiconductor protective type fuses are preferred. Alternate branch circuit protection devices are also listed in
the tables below.
This drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes,
480 Vac maximum (Up to 240 V in 200 V class drives, up to 480 V for 400 V class drives), when protected by fuses or
circuit breakers as specified in
Table 17 .
NOTICE: Equipment Hazard. Do not restart the drive or immediately operate the peripheral devices if a fuse is blown or a (GFCI) is
tripped. Check the wiring and the selection of peripheral devices to identify the cause. Contact your supplier before restarting the drive
or the peripheral devices if the cause cannot be identified.
