MDFU-/MDFU-E side: different distribution strips or carriers (Figure 4-14)
You can use a maximum of 9 CABLUs per MDFU (Figure 4-15) and 21 CABLUs per MDFU-E
(Figure 4-16) with a 16-TW terminal strip or 25-TW terminal strip (9 x 30 mm) each.
Use open-end cables for special cases of application where the prefabricated cables cannot be used.

Equipped with
SLMO8
or
SLMO24
Route 16 TW to the MDFU/MDFU-E via SU Xx8 and 8 TW via SU Xx9
using a standard cable (with 16 TW) for each connection. Both cables (= 1
CABLU whose SU connectors are labelled 8 and 9 respectively) are
connected to the same jumper strip (25 TW).
Existing standard CABLUs with splitting strips for 16 TW (e.g after
replacing an old system) can also be used. If SLMO24 is used, an
additional CABLU (SU Xx9) must be laid to the MDFU/MDFU-E.

connection is to be established via SU Xx9
(not via MDFU/MDFU-E).
