CHAPTER 3 - INSTALLATION
AND CONNECTION
ATTENTION!
The AC input for the inverter must have a grounded neutral
conductor.
EMI – Electromagnetic interference
When electromagnetic interference (EMI) generated by the
inverter interferes in the performance of other equipment, use
shielded wires, or install the motor wires in metallic conduits.
Connect one end of the shielding to the inverter grounding
point and the other end to the motor frame.

where the inverter is installed or ground it to the inverter. The
inverter output wiring must be laid separately from the input
wiring as well as from the control and signal cables.
NOTE!
Do not use neutral conductor for grounding purposes.
