UTILITY UNIT

HKU

HKU

HKU

*1: 

A dual-redundant configuration is enabled by using 2 identical modules with same model code (CP461 or CP471).

*2: 

The above diagram shows an example of ESB Bus wiring and its termination.

 

The wiring can be done from left to right or vice versa in between EC401 and ANT401 and among ANT421 modules.

*3:   For detail about FCU, refer to “FIO System Overview” (GS 33J60A10-01EN).
