Close the gateway cover, paying attention to the power supply
cable.
WARNING
Backup batteries, if present, may be connected only
after GSM400 has been supplied
Note:
the max voltage to be supplied to the mains terminal
G is 17Vdc.
Note:
the min voltage required to supply the GSM400
gateway by the mains terminal G is 10Vdc.
Note: a protection cut-out switch must be installed upstream
to interrupt power supply in case of fault.
Turning the GSM400 gateway on
Power the GSM400.
Wait 15 seconds after power-up to give time to the GSM400 to
register correctly with the GSM network.
Make sure the red LED (device status) flashes briefly once every 3
seconds as shown in chapter “SIGNALS”.
Set parameters or make a call.
If the red LED flashes quicker and stays lit for a longer time (see
“SIGNALS”), the GSM gateway has not properly registered with the GSM
provider. Disconnect GSM400 and make sure the SIM card is inserted
correctly and that the PIN is not locking it.
