Using the external power supply with the G110M AS-i variant
The 24 V power supply for the G110M AS-i variant is typically provided by the yellow and black
AS-i cables that create the AS-i network.
The yellow cable is the communications cable but also provides the power to:
• The Control Module
• The digital inputs
• The analog inputs
The black cable is the auxiliary cable and provides power to:
• Low voltage components of the Power Module
• The digital outputs
• The Fan (used with the Wall Mount Kit only).
The external 24 V power supply can be used in place of the black auxiliary cable (you cannot use
both at the same time), but the G110M AS-i must always use the yellow cable, as the G110M AS-
i cannot be used as a stand-alone converter.
Note
Loss of power to the 24 V external supply
If the mains supply to the converter is removed, then the external 24 V supply will lose power,
as it draws its power from the converters DC link. The yellow AS-i cable will still provide power
to the Control Module and the digital and analog inputs, so that the AS-i communications will
still be active.
