If you install at Ta 50°C environment, use copper wires that have a voltage rating of 600V and are
temperature resistance to 75°C or 90°C.
If you install at Ta 50°C above environment, use copper wires that have a voltage rating of 600V and
are temperature resistance to 90°C or above.
For VFD110C23A-21 models: if you install at Ta 45°C above environment, use copper wires that
have a voltage rating of 600V and are temperature resistance to 90°C or above.
To be UL installation compliant, you must use copper wires when installing. The wire gauge is based
on temperature resistance of 75°C, in accordance with UL requirements and recommendations. Do
not reduce the wire gauge when using high-temperature resistant wire.
