There are cable glands and plug sockets in the bottom of
the controller. The sockets for the plug connections are
pre-wired and pre-assembled in the controller housing.
Three plugs are included in the delivery. The plugs are
used to connect the pump accessories low water sensor,
remote float switch and solar panel for Sun Switch.
Accessories which use cable glands B1-B6 must be fixed
tightly in the glands for strain relief and sealing.
Preparing plugs – Cut the wire of the plug in half and
splice the cables of the corresponding pump accessory to it.
Use a proper crimping tool and sleeves matching the cable
size. If a plug socket isn't used set the mini plug into the
socket of the controller housing without cutting the cable
in half.

the solar panel for SunSwitch has a red (positive +) and a
black (negative –) cable. Ensure you have the correct polar-
ity. A voltage reversal will lead to damage of the controller.

socket for the plug to ensure correct plug installation.
