2. Installation
2.1. Installation Site
Only install the regulator near the battery on a suitable surface. This surface should be
solid, stabile, even, dry and nonflammable. The battery cable should be as short as pos-
sible and have a suitable cable diameter size to minimize loss, e.g. 4 mm² at 20 A and 2
m length.
If the solar battery will be operated under a large temperature range (winter/summer)
the external temperature sensor should be used. A temperature compensated final
charge voltage will extend the batteries lifetime and uses the optimum charge capacity
(see appendix).
Do not install the controller to direct sunlight.
To ensure the air confection on each side keep a distance of 10 cm to the regulator. The
temperature at the installation site may never fall below or exceed the maximal permit-
ted ambient temperature.

The integrated LC display should be protected against UV rays (e.g. sunlight). Chronic
exposure to UV rays can permanently discolor the LCD.
