modem OFF. For this, see the § 5.2 Turning the device OFF.
3.4.1 Power supply cables
The modem is powered with the cable supplied with the equipment (ERCOGENER P/N: 4402000107 or
4402304215). (See ANNEX 1 - 4-pin Micro-FIT cable without fuse)

See ANNEX 1 - ANNEX 1 - 4-pin Micro-FIT cable without fuse.
The pins 1 and 2 are used for the functions Input/Output.
The power supply to the modem is done only via the pins 4 (+VDC) and 3 (GND).
3.4.2 Power supply
The modem must be powered by an external DC voltage (+VDC) PS1 (max 15W) between:
Standard
+7.2V ≤ +VDC ≤ +32V
With battery option
+8V ≤ +VDC ≤ +32V
The modem is also internally protected against voltage peaks of more than 32 VDC.
The following table describes the consequences of an overvoltage or drop of voltage on the modem.
Table 8 : Effects of power supply defect
Then :
▪Voltage falls below 7.2V
▪The functioning and the radio communication are not
guaranteed.
▪Voltage falls below 8V
▪Battery charge will not be ensured.
▪Voltage above 32V (Punctual
peaks)
▪The modem guarantees its own protection.
▪Internal overcurrent
▪The modem is protected by an internal resettable
fuse.

3.4.3 Internal battery option (S0531)
This battery allows to maintain the operation of the GenPro 425e in case of absence of its external power
supply.
The internal charging circuit allows to keep permanently the charge of the battery from the external power
supply.
When the battery is completely discharged, 4 h 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 mainly depends on the mode of use of the GenPro 425e (attachment in
LTE/3G/GPRS/GSM, Inputs/Outputs, RS232 connected...).
In the case where the software management of the battery guarantees that the voltage VBAT
does not goes below 3,5 V. The autonomy depends on data volume, transmit power and
communication type 4G, 3G, 2G. With a new battery completely charged, the autonomy is
around:
Between 1h and 4h continuous data transfer, maximum transmit power, according type of
communication.
Up to 11h attached to the network without data transfer.
When the battery is charged, it is not possible to do an ON/OFF of the device. Only putting the
Reset input (pin 10 of the 16-pin Micro-FIT connector) to the Ground or sending the command
AT+EGMRST=0 allows a reset of the modem.
Below 0°C and above 45 °C inside the device, 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 this, see § 5.2 Turning the device OFF
Table 9 : Characteristics of the polymer lithium battery
The battery cannot be replaced or modified by the user; the device must never be opened.
For any intervention on the battery: the device must be returned to the factory.
Do not throw the modem and the battery on fire.
