WARNING:
Do not leave the switched off pasture fence device in the sun with a rechar-
geable battery and a solar panel for a longer period. Why? Because it could
damage the rechargeable battery.
OPERATING PRINCIPLE:
The solar panel produces electricity as soon as it is exposed to usable sunlight. The pasture fence device requires consistent
electricity - by day as well as by night. The electricity generated in this way by the panel is stored in a rechargeable 12 V
battery, which means the device can operate without sunlight or can be supplied directly by a
9 V battery. The solar panel may not always have a sufficiently large output to completely recharge the battery - especially
during the dark, grey and foggy months (e.g. October to February).
For temperatures around 0 degrees Celsius or below, we recommend using a large 9 V alkaline battery instead of a 12 V
rechargeable battery in any case.
The device is operated primarily from the solar panel. If the solar panel does not have sufficient output, the device switches
automatically to the connected 9 volt battery or to the 12 volt rechargeable battery.
OPTIMAL SOLAR ALIGNMENT AND SETTING
The correct placement of the pasture fence device and the solar panel is crucial for the best possible operation of the device.
1. POSITION THE PASTURE FENCE DEVICE SO THAT THE PANEL POINTS SOUTH.
This position provides the panel with the maximum amount of sunlight even during the less bright
winter days. When placing the device, consider the position of the sun throughout the day and avoid
a location which could cover the device with shade from trees, bushes or high grass.
2. DETERMINE THE CORRECT ANGLE OF INCLINATION FOR THE SOLAR PANEL.
The position of the sun over the horizon changes during the year's seasons. As a general recom-
mendation, an angle of 50 degrees is optimal for long-term use in most parts of Europe. Still, the ca-
pability of the solar panel to recharge the battery can be optimised by adjusting the angle, depending
on the season (see figure below). The steeper the angle of inclination, the greater the cleaning effect
during rain or snow.

During the winter (with the exception of southern Europe), there may not be enough sun hours to completely charge the
battery. Charge the battery externally as soon as the battery indicator flashes green/red or red, or alternatively use a large,
alkaline 9 V battery with 170–200 Ah, which is also recommended for temperatures around or below freezing.
3. REMOVE DEPOSITS AND DIRT FROM THE SOLAR PANEL AT REGULAR INTERVALS.
(specifically along gravel paths), leaves and snow, since these can reduce the performance of the module for recharging
the rechargeable battery.
SERVICE:
Repair is only to be made by qualified service personnel. Only by
the manufacturer commanded replacement parts must be used.
