UMI-B1 UL Series Inverter
3.2.3 Wiring of terminals in main circuit
1. Connect the ground line of input power cable to the ground terminal of inverter (PE)
directly, and connect 3PH input cable to R, S and T and fasten up.
2. Connect the ground line of motor cable to the ground terminal of the inverter, and
connect the 3PH motor cable to U, V, W and fasten up.
3. Connect the brake resistor which carries cables to the designated position.
4. Fasten up all the cables on the outside of the inverter if allowed.
