5.2 Specific recommendations for the use of the modem in vehicles
The power supply connector of the modem GenPro 2xe must
NOT
be connected directly to
the battery of the vehicle.
5.2.1 Recommended Connection on the battery of a truck
All lorries have a Circuit Breaker outside the cabin. The circuit breaker is used for security reasons: for
example, if a fire breaks out in the electric box of the lorry, the driver can cut off the power source and avoid
more damage (explosion).
The circuit breaker is connected to the ground of the lorry, usually connected to the fuse box.
Most of lorry circuit breakers do not cut off the PLUS of the battery, but cut off the ground.
GenPro 2xe
The scheme above shows a recommended power connection where the connection of the modem ground is
not directly connected to the battery, but connected after the circuit breaker (to the ground of the lorry or in
the fuse box).
