2.5.4
Applicable cables and wiring length
Select a recommended cable size to ensure that the voltage drop ratio is within 2%.
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 shows a selection example for the wiring length of 20 m (575 V input power supply).

It is 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 50°C or lower and in-enclosure wiring.

It is the gauge of the cable with continuous maximum permissible temperature of 90°C (THHN cable). It assumes a surrounding air temperature
of 40°C or lower and in-enclosure wiring.

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).
The screw size for earthing (grounding) terminal is indicated in parentheses.
