12V-SB-In Connector (J31)
The 12V-SB-In (12V StandBy power Input) connector is a 2 pin connector type Molex 22-23-2021or similar.
This connector can be used to add 12V Standby Power for use when 12V is not present on DC Power Internal
or DC Power External connectors.

The 12V (connected to pin 1) is connected to the 12V power rail via a diode to prevent reverse powering.
Maximum allowed supplied current is 1A, so power limitation feature must be built in the power circuit
connected to the 12V-SB-In connector.
Notes:
To protect the external power lines of peripheral devices make sure that
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
Alternatively the DC Power External Connector can be used
