 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 VFD2A5MS11ANSAA and VFD2A5MS11ENSAA 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.
 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.
