If you install at Ta 50°C environment, please select copper wire with voltage rating 600V and
temperature resistant 75°C or 90°C.
If you install at Ta 50°C above environment, please select copper wire with voltage rating 600V and
temperature resistant at 90°C or above.
For VFD220C23A, if you insall at Ta 40°C above environment, please select copper wire with
voltage rating 600V and temperature resistant at 90°C or above.
For UL installation compliant, please use copper wires for installation, the wire gauge is based on
temperature resistant at 75°C which is requested and recommended from UL. Do not reduce the
wire gauge when using higher temperature wrie.
Wire fix to pole +2/DC+ and +1/DC+ with 90 kg-cm / [78.2 lb-in] / [8.83 Nm] (±10%)
