4.2 System Installation
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.
