ABB Bailey IEFAN03 FAN ASSEMBLY MODULE

The power entry panel supplies line power to the system cabinet. There are three versions: IEPEP01, IEPEP02 and IEPEP03Power Entry Panel. The IEPEP01 panel is the basic version. Ithas surge protection and power fail interrupt detection; however, it does not have circuit breakers or DC voltage monitoringcapabilities. The IEPEP02 panel has one circuit breaker and isidentical to the IEPEP01 panel. The IEPEP03 panel has additional features.The IEPEP03 panel transfers redundant power to the systemcabinet and monitors system status. It contains the AC transfer module and the bus monitor module that perform thesefunctions. The AC transfer module monitors line voltage inputsto the system cabinet, provides automatic AC line transfer (forredundant AC lines) and generates a power fail interrupt (PFI)signal. The bus monitor module monitors the power systemand provides status and customer alarm outputs.
