Max. number of units to be connected
The following tables shows the maximum number of
units, which can be connected to a CU 5905 Central
Unit or to an EX 6010 Extension Unit or a PS 6000
.
Power Supply
In the tables the ‘Feeding Cable’ is defined as the
cable between the CU 5905 (or EX 6010 / PS 6000)
and the first DC 5980P and the ‘Interconnecting Cable
is defined as the cable connecting two DC 5980P.
4.4.1
CU 5905 – DC 5980P, one chain
The following table shows the maximum number of
units, which can be connected to a CU 5905 Central
Unit when using only one of the two ‘Chain’ outputs.
The table also shows the number of units, which can
be connected to each ‘Chain’ output on an EX 6010
Extension Unit or to the ‘Chain’ output of a PS 6000
Power Supply.

The following table shows the maximum number of
units, which can be connected to both ‘Chain’ outputs
simultaneously on a CU 5905 Central Unit in total
using only the supplied CU 5900 Power Supply.
If only one ‘Chain’ is used the information in the table

CU 5905 – DC 5980P – JB 6104,
one chain
This configuration shows two DC 5980P Conference
Units each connected to an output on a JB 6104
Junction Box with 3m cables between each JB 6104.
General
note:
Maximum cable length from a JB 6104
to a DC 5980P is 5 m and maximum one DC 5980P is
allowed on each output of a JB 6104.
