WIRING
2.2.3 Cables and wiring length
(1) Applicable cable size
Select the recommended cable size to ensure that a voltage drop will be 2% or less.
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.
400V class (when input power supply is 440V based on the rated current for 110% overload for 1 minute)
The line voltage drop can be calculated by the following formula:
Line voltage drop [V]=
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque
reduction) in the low speed range.

with continuous maximum permissible temperature of 90°C. Assumes that the surrounding air temperature is 50°C or less and wiring is performed in
an enclosure.
*2 For the 00930 or less, 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.
For the 01160 or more, the recommended cable size is that of the cable (THHN cable) with continuous maximum permissible temperature of 90°C.

Assumes that the surrounding air temperature is 40°C or less and wiring is performed in an enclosure.
(Selection example for use mainly in the Europe.)
*4 The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, P/+, N/-, P1, and a screw for earthing (grounding).
A screw for P/+, N/-, and P1 of the 01800 is indicated in ( ).
A screw for P/+ terminal for option connection of the 03250 and 03610 is indicated in ( ).
A screw for earthing (grounding) of the 04320 or more is indicated in ( ).
CAUTION
· Tighten the terminal screw to the specified torque. A screw that has been tighten too loosely can cause a short circuit or
malfunction. A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.
· Use crimping terminals with insulation sleeve to wire the power supply and motor.
