3�5�- EXPANSION WITH OTHER DEVICES
The
line-CVM-D32
devices can be expanded with other devices in the Line range, and with the
line-
EDS
and
line-M
expansion modules .
The
line-EDS
and
line-CVM
devices
enable up to 2 expansion modules to be directly connected to their
right-hand side

Expansion module types:
line-M-4IO-R
,
line-M-4IO-T, line-M-4IO-RV, line-M-4IO-A, line-M-20I and line-TCPRS1�
The
line-M-3G
module can only be connected on the left side of
line-EDS
devices. If the
line-EDS
has
a
line-M-3G
connected to it, only 1 expansion module can be connected on its right side.
In installations with
line-EDS
devices
,
a total of up to seven devices may be connected to their right-
hand side.

Figure 5: Typical installation of a line-EDS with 7 devices�
Note:
An installation may only be fitted with one
line-EDS
device
.
Note:
In installations without
line-EDS
devices
,
only one
line-CVM
device may ne installed.
Note:
All
line-EDS
and
line-CVM
devices
must be connected to the auxiliary power supply.
