Note: 1. The cables used should be 75°C (167°F) copper cables.
2. Tighten the terminal screws to the specified torque.
Undertightening can cause a short or misoperation.
Overtightening can cause the screws and unit to be damaged, resulting in a short or
misoperation.

The power supply cables
must be connected to R, S, T.
If they are connected to U, V,
W, the inverter will be damaged.
Phase sequence need not be
matched.
For use with a single-phase
power supply,the power supply
cables must be connected to
R and S.
Connect the motor to U, V, W.
In the above connection,
turning on the forward rotation
switch (signal) rotates the motor
in the counterclockwise (arrow)
direction when viewed from
the load shaft.
