3.5 Protections
The modem is protected by a fuse directly bonded on the power supply cable.
The model of fuse used is: F 2.5 A L 250 V.
The modem is also protected against voltage over +32 V.
When input voltages 32 V, the supply voltage is disconnected in order
to protect the internal electronic components from an overvoltage.
Filtering guarantees:
EMI/RFI protection in input and output,
Signal smoothing.
