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

Main Circuit Terminal Wiring
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 CIMR-L20085 to
20415 and 40045 to 40216. Use only the tools recommended by the terminal manufacturer for crimping.
The wire gauges listed in the tables below 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 IEC/EN 60417-5019)
