Connecting to the power supply

Connecting the modem module to a live power supply can damage the module. Connect
the modem to the power supply only when the power supply is off.
The power for the device (24 V DC) must be generated as a safe extra low voltage. This
means it must be a SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low
Voltage) according to DIN VDE 0100 Part 410 (IEC 60364-4-41).
