TECDrive20-EU Series Inverter Installation guidelines
-19-
Note:
 Do not use asymmetrically motor cables. If there is a symmetrically grounding conductor in
the motor cable in addition to the conductive shield, connect the grounding conductor to the
grounding terminal at the inverter and motor ends.
 Route the motor cable, input power cable and control cables separately.
3.2.3 Wiring of main circuit terminals
1. Connect the ground wire of the input power cable to the ground terminal (PE) of the inverter,
and connect the 3PH input cable to the terminals R, S, and T, and fasten them up.
2. Connect the ground wire of the motor cable to the ground terminal of the inverter, and
connect the 3PH motor cable to the terminals U, V, and W, and fasten them up.
3. Connect the braking resistor and other accessories that are equipped with cables to the
specified positions.
4. Fasten all the cables outside of the inverter mechanically, if possible.
