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 § 5.9 Turning off the modem
The following table describes the consequences of over-voltage or insufficient voltage on the modem.
Table: Effects of a power supply defect
Then:
▪
Voltage falls below 5.5V
▪
The functioning and the GSM 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
supply cable.
The modem does not have any internal protection. For that, you must use the supply cable
provided with the modem which has this protection.
The following tables show the modem consumptions
depending on the different functions activated.
