4. Power connections
4.1.12.0V DC power connection
The G031 module can be supplied by 12.0-24.0V DC power. Connect a 12.0V DC power supply to the
power input screw terminals and switch on the power supply. The red system LED will flash at 1 second
intervals once the system has finished initialization. The blue network LED indicator will initially flash
quickly and, once logged onto the network, it will flash more slowly, approximately once every 3 seconds
4.2.Battery connections
The G031 supports backup battery inputs. The battery can be an auxiliary power supply for operation
during mains power failure. A 12.0V rechargeable Li-ion or Lead-acid battery can be connected to battery
input terminals on the G031.
Connection to a battery can allow the G031 to operate for up to a few days (depending on the battery
capacity) without mains power. The G031 will alert the operator when mains power has been lost and
recovered. The battery will recharge when power is restored. When recharging the battery, the mains
power input should be at least 2.0V higher than the battery’s full voltage level. Therefore, the mains
power supply voltage should be 14.0-24.0V.
