Sequence of solar pumps installation
Open the package and check the product entirely
The control switch must be in position
”OFF” (“0” position)
Connect the photovoltaic module(s), accumulator (only if used in the relevan case), pump and
level sensors cables to the cable terminal of the controller in agreement with the connection
scheme. Choose the right cable dimension, fuses, switches and water level sensors.
Tight the fixing screws at the cable terminal with a screwdriver.
Be sure that the photovoltaic module(s) deliver power enough to the controller.
After finishing the upper steps, switch on the control switch (position I), the motor will operate for
10 seconds, after that will stop for 30 seconds (self-test), if the cables and the installation are
right, the pump will restart and work without interruption.
If the pump doesn't work properly, please check the operating indicators and the fault
indications, to find the reason and contact the supplier.
Mount the controller in a dry and well ventilated place.
Never expose the controller in outer
atmospheric effect
– the controler is not waterproof, and this will lead to its damage.
!!! Notes
The pump must be immersed in the water 15-20 minutes before its first starting. DO NOT
START THE PUMP DRY!, not even for test switching on. The working depth should not be
under 0,5m. It is not recommended the installation of the pump in depth bigger than 20m
under the water level.
During the installation of the submersible pump, there must be a rope connected to it.
Don't lift up the pump through the electric cable, the warranty will be refused if it gets
damaged.
The motors' supplying cables (U,V,W), must be connected to the controllers' cable
terminal (U,V,W) in the right way. Otherwise the motor will reverse and the pump will not
extract any water or very little water.
The water level sensor should be put over pumps' suction level. Otherwise it won't be
able to prevent the pump running dry. If there is no need of level sensor installation,
terminal WH and terminal WC (COM1) should be shortcut-connected.
You must make sure that the pump is positioned on the right depth. The stopping
between the switches ON and OFF should be at least 3 minutes or the pump protection
will be activated and the pump will stop working.
If there is a need of controllers' parameters change, the cover should be opened very
carefully to prevent the interruption of the inner connections.
