ACHTUNG
The power supply cables must be connected to R/L1, S/L2, T/L3. (Phase sequence needs not to be matched.) Never connect the
power cable to the U, V, W of the inverter. Doing so will damage the inverter.
Connect the motor to U, V, W. At this time turning on the forward rotation switch (signal) rotates the motor in the clockwise direction
when viewed on the motor shaft.
