LMFC cable (heat resistant flexible cross-linked polyethylene insulated cable), etc. with a continuous maximum permissible temperature of 90°C
or higher. It is assumed that the cables will be used in a surrounding air temperatures of 50°C or less and housed in an enclosure.

THHN cable with a continuous maximum permissible temperature of 90°C. It is assumed that the cables will be used in a surrounding air
temperatures of 40°C or less and housed in an enclosure.

The screw size for terminals R/L1, S/L2, T/L3, U, V, W, P/+, N/-, and the earthing (grounding) terminal are shown.
The size of the earthing (grounding) screw is indicated in parentheses.
The line voltage drop can be calculated by the following formula:
× wire resistance [mΩ/m] × wiring distance [m] × current [A]
Line voltage drop [V] =
Use a larger diameter cable when the wiring distance is long or when the voltage drop (torque reduction) in the low speed range
needs to be reduced.
NOTE
• Tighten the terminal screw to the specified torque.
A screw that has been tightened too loosely can cause a short circuit or malfunction.
A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.
• Use crimp terminals with insulation sleeves to wire the power supply and motor.
