5  Use of the modem 

5.1  Specific recommendations for the use of the modem in vehicles 

 

 

The power supply connector of the modem GenPro 25e must NEVER be connected directly 
to the battery of the vehicle. 

 

5.1.1 

Recommended connection on the battery of a truck 

All trucks have a circuit breaker outside the cabin. The circuit breaker is used for security reasons: 

The circuit breaker is connected to the ground of the truck, usually connected to the fuse box. 

Most of truck circuit breakers do not cut the

PLUS

GROUND

'. 

 

Figure 26 : Recommended connection on the battery of a truck

 

 

 

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 (on the ground of the truck or in 

the fuse box). 

 

 

If  this  scheme  is  not  respected,  the  modem  can  be  damaged  when  starting  the  truck  if  the 
circuit breaker is open. It cannot support important starting currents.
