Introduction
Set up the connection between the MDFU or MDFU-E and the system using CABLUs (prefabricated cabling units) with the following characteristics:
![]() |
System side: SIPAC 1 SU connector |
![]() |
Cable: 16 x 2 x 0.4 (the standard cable length is 2 m.) |
![]() |
MDFU-/MDFU-E side: Different distribution strips or carriers (Figure 4-28) |
You can use up to 9 CABLUs per MDFU (Figure 4-29) and 21 CABLUs per MDFU-E (Figure 4-30), each with a 16 TW terminal strip or a 25 TW terminal strip (9 x 30 mm).
Use open-end cables for special applications in which the prefabricated CABLUs cannot be used.

From the hardware point of view, EC2 is installed between the BC and EC1. |
Expanding a Two-Cabinet "7-Slot" System to a Three-Cabinet "7-Slot" System (Not for U.S.)
The new cabinet (EC2) is already equipped with a CONBO board (slot 17). Because it does not have terminating resistors, EC2 must be installed between the BC and EC1.
Terminating Resistors in "7-Slot" Cabinets
![]() |
BC: Between slots 3 + 4 and 7 + PSUI/UPSM |
![]() |
EC1: Between slots 11 + 12 and 15 + PSUI/UPSM |
![]() |
EC2: No terminating resistors |
![]() |
The "8-slot" basic cabinet has seven slots, while the expansion cabinets each have eight slots for peripheral boards. You cannot install both "7-slot" cabinets and "8-slot" cabinets in the same system. |

Expanding a Two-Cabinet System to a Three-Cabinet System (for U.S. Only)
The new cabinet (EC2) is already equipped with a CONBO board (Slot 17). Because it does not have terminating resistors, EC2 must be physically installed between the BC and EC1 by re-running the cables from BC to EC1 so that they now run from BC to EC2 (compare Figure 4-26 on page 4-48 and Figure 4-27).
