Main circuit terminals
2.5.4
Applicable cables and wiring length
Select a recommended cable size to ensure that the voltage drop will be 2% or less.
If the wiring distance is long between the inverter and motor, the voltage drop in the main circuit will cause the motor torque to
decrease especially at a low speed.
The following table indicates a selection example for the wiring length of 20 m.


The gauge of the cable with the continuous maximum permissible temperature of 90°C or higher. (LMFC (heat resistant flexible cross-linked
polyethylene insulated cable), etc.). It assumes a surrounding air temperature of 40°C or lower and in-enclosure wiring.

The recommended cable size is that of the cable (THHN cable) with continuous maximum permissible temperature of 90°C. It assumes a
surrounding air temperature of 40°C or lower and in-enclosure wiring.
(Selection example for use mainly in the United States.)

The cable size is that of the cable (XLPE cable) with continuous maximum permissible temperature of 90°C. It assumes a surrounding air
temperature of 40°C or lower and in-enclosure wiring.
(Selection example for use mainly in Europe.

The terminal screw size indicates the size of a terminal screw for R/L1, S/L2, T/L3, U, V, W, P/+, N/-, and a screw for earthing (grounding).
Screw size for earthing (grounding) is indicated in parentheses.
