3.4 Power supply
If the battery is present, the fact of removing the power V
DC
will not turn the modem
OFF. For this, see the § 6.2 Turning the modem OFF
3.4.1 Power supply cables
The modem is powered with the cable supplied with the equipment (ERCOGENER reference: 4402304215).
(See ANNEX 1 – 4-pins Micro-FIT cable (4 wires, Power supply))
The modem is protected by a fuse F2 A / 32 V directly assembled on the power cable supplied with the
modem.
The power cable supplied with the modem must be absolutely used; without this cable, the
modem will not be protected.
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 (+V
DC
) and 3 (GND).
The modem must be powered by an external DC voltage b8V
DC
and +32V
DC
.
The internal regulation is done by a DC/DC converter and allows the supply of all necessary internal DC
voltages.
The modem is also internally protected against voltage peaks of more than 32 V
DC
.
The following table describes the consequences of an overvoltage or drop of voltage on the modem.
3.4.2 Power supply 8 – 32V
DC
The following table describes the consequences of an overvoltage or drop of voltage on the modem.
Table 5 : Effects of power supply defect
Then:
▪ The functioning and the GSM and GNSS
communication are not guaranteed when the
remaining capacity of the battery is not sufficient. ▪ Voltage falls below 8V
▪ Voltage above 32V (Punctual
peaks)
▪ The modem guarantees its own protection.
▪ The modem is protected by the fuse assembled on
the power supply cable in combination with the
internal protection.
▪ Voltage above 32V (Continuous
overvoltage)
