Wiring the Output Side of Main Circuit
Observe the following precautions when wiring the main output circuits.
Connecting the Inverter and Motor
Connect output terminals U/T1, V/T2 and W/T3 to motor lead wires U, V and W, respectively.
Check that the motor rotates forward with the forward run command. Switch over any two of the output termi-
nals to each other and reconnect if the motor rotates in reverse with the forward run command.
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals U/T1, V/T2 and W/T3. If voltage is applied to the output
terminals, the internal circuits of the Inverter will be damaged.
Never Short or Ground Output Terminals
If the output terminals are touched with bare hands or the output wires come into contact with the Inverter cas-
ing, an electric shock or grounding will occur. This is extremely hazardous. Do not short the output wires.
Do Not Use a Phase Advancing Capacitor or Noise Filter
Never connect a phase advancing capacitor or LC/RC noise filter to an output circuit. The high-frequency
components of the Inverter output may result in overheating or damage to these part or may result in damage
to the Inverter or cause other parts to burn.

Do not use general-purpose noise filters. No general
purpose noise filter can effectively suppress noise
generated from the Inverter.
