Installation
Figure 2.18 illustrates the wiring between the FACP's Secondary ANN-BUS and ANN-BUS devices.
Powering Both ANN-BUS Circuits Simultaneously
When simultaneously using the Primary and Secondary ANN-BUS circuits on the FACP, power can be shared from the Nonresettable Power
output on TB11. Alternately, one ANN-BUS can be powered by the Resettable Power output (TB11 Terminals 3 and 4) once it is reconfig-
ured as Nonresettable Power in panel programming. This provides the benefit of independently acting power-limiting for the two ANN-BUS
circuits (required for Canadian applications).
Powering ANN-BUS Devices from an Auxiliary Power Supply
Figure 2.19 illustrates the powering of ANN-BUS devices from an auxiliary power supply such as the FCPS-24FS6/8, when the total ANN-
BUS power requirements exceed the panel's DC Power Output capability.
