Connecting the GPRS modem to the battery and solar panel
Before connecting the solar panel to the modem, temporarily cover the panel with cardboard to
prevent any current from being generated during the installation.
1. Feed the black cable from the solar panel through the strain relief on the bottom of the Modem
Enclosure.
2. Attach the black and red solar panel wires to the green circuit board as diagrammed below. The
black wire attaches to the second slot from the bottom. The red wire attaches to the first slot from the
bottom. The slot is opened by loosing up the screw with a small screwdriver. Before tightening on the
screws insert the tinned leads into the holes. Next, tighten the screws completely. Repeat for the
second wire. Give the wires a slight tug to ensure they are attached securely.
Note: Attaching the solar panel wires can be a little challenging. If you are having difficulty, try using a
needle-nose plier to help push the wires into the slots.
