*1
For the 01160 or less, the recommended cable size is that of the HIV cable (600V class 2 vinyl-insulated cable) with continuous
maximum permissible temperature of 75°C. Assumes that the ambient temperature is 50°C or less and the wiring distance is 20m or
less.
For the 01800 or more, the recommended cable size is that of the LMFC cable (heat resistant flexible cross-linked polyethylene
insulated cable) with continuous maximum permissible temperature of 90°C. Assumes that the ambient 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 THHW cable with continuous maximum permissible temperature of
75°C. Assumes that the ambient 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 THHN cable with continuous maximum permissible temperature of
90°C. Assumes that the ambient temperature is 40°C or less and wiring is performed in an enclosure.
(Selection example for use mainly in the United States.)
*3
For the 00930 or less, the recommended cable size is that of the PVC cable with continuous maximum permissible temperature of
70°C. Assumes that the ambient 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 XLPE cable with continuous maximum permissible temperature of
90°C. Assumes that the ambient temperature is 40°C or less and wiring is performed in an enclosure.
(Selection example for use mainly in Europe.)

The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, and a screw for earthing.
A screw for P/+, N/–, and P1 of the 01800 is indicated in brackets.
A screw for P/+ terminal for option connection of the 03250 and 03610 is indicated in brackets.
A screw for earthing (grounding) of the 04320 or higher is indicated in brackets.
The line voltage drop can be calculated by the following expression:
3
---------------------------------------------------------------------------------------------------------------------------------------------------------------------
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.
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.
