3.5. Plug the device to the external battery
The device must have a direct connection with the main power (external battery). Mobile
Devices advise against the use of intermediate system.
1.
Check that inputs 2 and 3 are free (not connected).
2.
Plug the device (black wire) to the ground of the external battery.
3.
Plug the device (red wire) to the permanent positive of the external battery.
4.
Plug the device (white wire) to the ignition (after contact).
In some case, the use of a circuit breaker can let the ignition (after contact) active. Thus, the
device will be ON indefinitely. So, it’s important to find a signal where the ignition can be
ON or OFF.
Moreover, it is imperative to insulate the GPS antenna in order to avoid it get in touch with
the car’s chassis.
The device should be always plugged to
:
•
The ground of the external battery.
•
A ground point defined by the vehicle manufacturer.
A circuit breaker should never be enabled as long as
:
•
Ignition is active.
•
Ignition goes OFF since less than 2 minutes. This is the time for the device
to do a proper shutdown.
It is mandatory to add a fuse (2A) to the permanent positive. The closer to the
connection point with vehicle power.
4. Inputs activation threshold
Here are inputs activation thresholds (voltage).
•
Input2 (negative) is active from approx. 0 to 2V (disabled if >2V)
•
Input3 (negative) is active from approx. 0 to 2V (disabled if >2V)
Note
: Range voltage on inputs is 0-30V
