Once the power supply is connected, the modem is permanently consuming.
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 § Turning
The following table describes the consequences of over-voltage or insufficient voltage on the modem.
Table 40 : Effects of power supply defect
Then:
▪ Voltage falls below 7.2V
▪ The functioning and the GSM and GPS
communication are not guaranteed when the
remaining capacity of the battery is not sufficient.
▪ Voltage above 32V (Punctual
peaks)
▪ The modem guarantees its own protection.
▪ Voltage above 32V (Continuous
over-voltage)
▪ The modem is protected by the fuse mounted on the
power supply cable.
The modem does not have any internal protection. For that, you must use the power supply
cable provided with the modem which has this protection.
