CAUTION
•
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.
Turning on the forward rotation switch (signal) at this time rotates the motor
counterclockwise when viewed from the load shaft.
