PART 1 - QUICK INSTALLATION GUIDE
ELECTRICAL CONNECTIONS
Before making the connections, make sure that:
-
the ends of the line wires are not live.
-
the electric power supply network is protected by thermal magnet and differential
protection high-sensitivity type
(30 mA in class A for domestic application, class B for
industrial applications)
Ground connections must be in compliance with Standards.

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
