7.3 Power supply
7.3.1
General presentation
The modem must be powered by an external DC voltage (V+BATTERY) b7.2V and +32V.
The regulation of the modem power supply is made with a DC/DC internal converter in order to supply all the
necessary internal DC voltages.
For the GPS module, another regulation is made for its internal power supply.
A correct functioning of the equipment is not guaranteed if the Input voltage (V
DC
) falls below
7.2 V and if the battery is not charged enough.

Internal battery
7.3.2.1
Presentation of the internal battery
The battery is fixed inside the GenLoc 54e. It is connected to an additional charging circuit cabled on the
motherboard of the GenLoc 54e.
This battery allows to maintain the GenLoc 54e functioning in case of absence of its external power supply
(power supply connected on the Micro-FIT 4-pin female connector).
The internal charging circuit allows to keep permanently the charge of the battery from the external power
supply.
When the battery is completely discharged, 3 hours are necessary to obtain a new complete charge. It is
normal if the box is becoming a little bit hot in this case.
The autonomy of the battery essentially depends on the mode of use of the GenLoc 54e (attachment in
GSM/GPRS, Inputs/Outputs, GPS power supply, RS232 connected...).
As an information, the autonomy is around 9H with the following conditions:
GSM attached to GPRS network without data transfer.
Serial link not connected.
GPS OFF
No Input Output connected
When the temperature exceeds 45 °C inside the box, the protection of the battery management
triggers. The battery will not be charged.
If the battery is present, prepare the modem for storage or transport conditions, in order to
limit high discharges of the battery. For that, see § 5.11 Turning OFF the modem
