Recommendations When Using the
GL61x0 on Trucks
14.2. Technical Constraints on Trucks
It is highly recommended to directly connect the power supply on the circuit breaker rather than on the
battery. The GL61x0 may be damaged when starting the truck if the circuit breaker is switched OFF
(in this case, the truck ground and the battery ground will be connected through the GL61x0 as shown
in the following figure).
Figure 31. Example of an Electrical Connection Which May Damage the GL61x0
The figure above gives an example of an electrical connection which may dramatically damage the
GL61x0 when its ground connection is directly connected to the battery ground.
In this example, when the circuit breaker is switched OFF, the current flows through the GL61x0 and
powers the electrical circuit of the truck (for example, the dashboard).
Furthermore, when the Starter Engine command is used, it will destroy the cables or the GL61x0.
Since the internal tracks of the GL61x0 are not designed to support high currents (up to 60A when
starting the truck), they will be destroyed.
