Installation of solar controller

10.1 Appliance installation
Always disconnect from the mains before opening the
controller cover.
The solar controller is designed to be mounted on the front of
the pump station. Alternatively it can be removed from the
insulation and be wall mounted (see panel below). In the case
of wall mounting the pump cable may need to be lengthened.
Alternative mounting option
In the case of wall installation proceed in the
following way:
Drill installation holes according to the dimensions
shown below. Screw in two upper screws up to 6 mm
distance. Open the appliance as described in section 10.2
and hang it onto two screws. Now two lower screws can be
mounted.Tighten all screws. Do not overtighten to avoid
damage to the controller backplate.
