NOTE:
1. For installation at an ambient temperature of 50°C, select copper wires with temperature resistance of
75°C or 90°C. For installation at an ambient temperature over 50°C, select copper wires with temperature
resistance of 90°C or above.
2. For VFD007EL21W(-1) model: when install at Ta 40°C environment, use copper wires that are temperature
resistance to 75°C or 90°C; when install at Ta 40°C above environment, use copper wires that are
temperature resistance to 90°C or above.
3. When installing VFDxxxEL21W(-1), use wires that have a voltage rating of 300 V
AC
or above. When
installing VFDxxxEL43W(-1), use wires that have a voltage rating of 600 V
AC
or above.
