2.3 Design

2.3.1 Design of Hicom 150 E OfficePro

Three variants
Depending on requirements, Hicom 150 E OfficePro can be used as:
a one-cabinet system (BC)
a two-cabinet system (BC + EC1)
a three-cabinet system (BC + EC1 + EC2)
Configuration notes
The basic cabinet (BC) and expansion cabinet 1 (EC1) have the same design. Expansion cabinet 2
(EC2) differs from the other two cabinets in that there is no terminal resistance.
Up to two cabinets can be stacked. Six slots in each cabinet (slots 2-7) are available for peripheral
boards. Fixed slots are assigned to the PSUI power supply unit (in all cabinets), CBMOD control
board (BC only) and the CONBO board (EC2 only). A main distribution frame (MDFU/MDFU-E) is
needed to complete the communication system.
