(1) Cable sizes etc., of the main control circuit terminals and earth (ground) terminals
Select the recommended cable size to ensure that a voltage drop will be 2% max.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to
decrease especially at the output of a low frequency.
The following table indicates a selection example for the wiring length of 20m.

∗1
The cable size is that of the cable (HIV cable (600V class 2 vinyl-insulated cable) etc.) with continuous maximum permissible temperature of 75°C. Assumes
that the surrounding air temperature is 50°C or less and the wiring distance is 20m or less.
∗2
The recommended cable size is that of the cable (THHW cable) with continuous maximum permissible temperature of 75°C. Assumes that the surrounding air
temperature is 40°C or less and the wiring distance is 20m or less. (Selection example for use mainly in the United States.)
∗3
The recommended cable size is that of the cable (THHW cable) with continuous maximum permissible temperature of 70°C. Assumes that the surrounding air
temperature is 40°C or less and the wiring distance is 20m or less. (Selection example for use mainly in Europe.)
∗4
The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, and a screw for earthing (grounding).
A screw for earthing (grounding) of the FR-E720-15K is indicated in ( ).
For single-phase power input, the terminal screw size indicates the size of terminal screw for R/L1, S/L2, U, V, W, PR, P/+, N/-, P1 and a screw for earthing
(grounding).
