Installing a Noise Filter on the Power Supply Side
The Inverter’s outputs utilize high-speed switching, so noise may be transmitted from
the Inverter to the power line and adversely affect other devices in the vicinity. It is rec-
ommended that a Noise Filter be installed at the Power Supply to minimize this noise
transmission. Conversely, noise can also be reduced from the power line to the Inverter.

Note
Use a special-purpose Noise Filter for the SYSDRIVE 3G3MV. A general pur-
pose noise filter will be less effective and may not reduce noise.
Please, use the noise filters as explained in Chapter 9-2.

Wiring on the Output Side of the Main Circuit
D
Connecting the Terminal Block to the Load
Connect output terminals U/T1, V/T2, and W/T3 to motor lead wires U, V, and W.
Check that the motor rotates forward with the forward command. Forward means shaft
of the AC motor rotates in CCW (Counter Clock Wise), if you look from shaft to motor
end. Switch over any two of the output terminals to each other and reconnect if the motor
rotates in reverse with the forward command.
D
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals U/T1, V/T2, or W/T3.
If voltage is applied to the output terminals, the internal circuit of the Inverter will be dam-
aged.
D
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 casing, an electric shock or grounding will occur. This is extremely haz-
ardous.
Also, be careful not to short the output wires.
