3 Electrical Connection
3.1Outlet filter system installation and connection
The outlet filter connected between inverter and water pump. System
optimization for long cable reflect in the following 3 points:
(1) Effective control of motor reflected voltage, protect motor
insulation, prolong the lifespan of pump;
(2) Effective suppress the surge voltage on the electric cable, protect
inverter power module;
(3) Filter out PWM control high frequency harmonic, pump running
more stable, improve system efficiency.
Fig.3-1 Outlet filter system connection sketch map
Input and output terminal of outlet filter installed in the bottom, all of
them are M25 water-proof, as is showing Fig.3-2.Output cable switch
in outlet filter through the terminal of “INVERTER”, and output cable
of outlet filter switch in terminal of pump motor through “MOTOR”
3.2 Outlet Filter Internal Wiring
There are input and output terminal, users need to open the latch in the
bottom right side and bottom cover plate. Output cable of inverter
connected “U, V, W” three phase terminal array and cable of pump
connected with “A, B, C” three phase terminal array respectively, as the
Fig. showing:
