POWER CONNECTIONS
Open the side cover
(4 screws)
Wire the cables as indicated in the
diagrams below:
A = inverter supply cable
B = output motor cable
Insert the connector and close
the side cover.
CAUTION : to overcome problems associated with long cables (between Inverter
and pump motor) , evaluate the application of inverter output sinusoidal filter. It aids
smooth running of motors eliminating negative effect of voltage peaks
