2.5 Installation of battery in the sensor

The sensor's primary power sources are the in-built solar panels and
the field probe, which obtains the energy respectively from the sun
and the electrical field surrounding the surge arrester. The energy is
stored in a high efficiency capacitor.
When energy in the sensor falls below a certain level, the sensor swit-
ches off the listening function (to conserve energy for recording) until
such time that the energy level is sufficient again for communication.
This may occur if many attempts to communicate have been made in
a row or because there is insufficient sunlight and/or electrical field.
To ensure continuous power a long-life 9V lithium battery may be
installed.
Installation of a battery is an absolute necessity for indoor use of
the sensor, since no sunlight is available to provide the primary
source of power.
NOTE! A long-life battery is pre-installed from the factory for user con-
venience to minimize difficulties in communication due to insufficient
energy. Regardless, it is highly recommended that the internal high-
efficiency capacitor is fully charged before first-time use by following
the steps in section 2.4 b.
To replace the battery, open the battery cover using the supplied phi-
lips screwdriver to loosen the two screws, see figure 2.5.1. Insert the
battery, ensuring correct polarity, and then replace the battery cover.
