 If you install at Ta 50°C
above environment, select copper wire with voltage rating of 600 V and
temperature resistance of 90°C or above.

If you install at Ta 50°C environment, select copper wire with voltage rating of 600 V and temperature
resistance of 75°C or 90°C.
 For VFD33AMH23ANSAA, VFD33AMH23ENSAA models: If you install at Ta 40°C above
environment, select copper wire with voltage rating of 600 V and temperature resistance of 90°C or
above.
 For VFD49AMH23ANSAA, VFD49AMH23ENSAA models: If you install at Ta 35°C above
environment, select copper wire with voltage rating of 600 V and temperature resistance of 90°C or
above.
 For VFD32AMH43ANSAA, VFD32AMH43ENSAA, VFD32AMH43AFSAA models
: If you install at Ta
45°C above environment, select copper wire with voltage rating of 6
00 V and temperature resistance
of 90°C or above.
 For UL installation compliance, 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 wires.
 ** These drives must be wired with the specified ring lug dimensions.
