NOTE: 
1.  If you install at Ta 45°C environment, select copper wire with voltage rating of 600 V and temperature 
resistance of 75°C or 90°C 
2.  If you install at Ta 45°C above environment, select copper wire with voltage rating of 600 V and temperature 
resistance of 90°C or above. 
3.  For UL installation compliance, use copper wires when installing. The wire gauge is based on a temperature 
resistance of 75°C, in accordance with UL requirements and recommendations. 
4.  Do not reduce the wire gauge when using higher temperature wire. 
5.  For VFD220VL43A-J model, if you install it at Ta 30°C above environment, select copper wire with voltage 
rating of 600V and temperature resistance of 90°C or above.
