If you install at Ta 50°C above environment, use copper wires that have a voltage rating of 600 V and
are temperature resistant to 90°C or above.
If you install at Ta 50°C environment, use copper wires that have a voltage rating of 600 V and are
temperature resistant to 75°C or 90°C.
For VFD33AMS23ANSAA and VFD33AMS23ENSAA models: If you install at Ta 40°C above
environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to
90°C or above.
For VFD49AMS23ANSAA and VFD49AMS23ENSAA models: If you install at Ta 35°C above
environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to
90°C or above.
For VFD32AMS43ANSAA, VFD32AMS43ENSAA, and VFD32AMS43AFSAA models:
If you install at Ta 45°C above environment, use copper wires that have a voltage rating of 600 V and
are temperature resistant to 90°C or above.
To be UL installation compliant, you must use copper wires when installing. The wire gauge is based
on a temperature resistance of 75°C, in accordance with UL requirements and recommendations.
Do not reduce the wire gauge when using high-temperature resistant wires.
**Wire these drives by ring lugs with specified dimensions.
