CPX-E modules
The CPX-E modules are designed in such a way that an exchange of individual com
ponents is possible without dismantling the CPX-E system. By disengaging the
interlock of the terminal strips, you can remove them from the module. By disenga
ging the interlock of the module, you can remove an individual module from the
system. The link remains on the H-rail.

5.3 Display components
The CPX-E modules have LED indicators specific to the module, network or system:
– LED indicators specific to the module or network are described in the document
ation for the respective module.
– An overview of the system-specific LED displays is displayed in the following
table
è
Fig. 5.
– The behaviour of the system-specific LED indicators is described in “Description
of the CPX-E system” (

5.4 Control elements
A CPX-E module has interlocks for
engaging and disengaging the module
terminal strips and connected
conductors.

5.5 Connecting components
Connection of the CPX-E system
The individual modules of a CPX-E system are connected to each other through the
link. The contact to the link is established when the modules are hung into the
H-rail
è
7 Mounting. If a module is removed, the connection to the other modules
is interrupted.
Connecting peripheral equipment
For the connection of the peripheral equipment, the modules have terminal strips
with spring-loaded terminals

Mounting
7.1 H-rail mounting
The modules can be mounted to an H-rail 35 × 7.5 mm according to EN 60715.
When selecting screws for H-rail mounting, a distance between the H-rail
and the linking elements of 3 mm must be observed.
The distance between the mounting screws of the H-rail may be a max
imum of 50 mm.
7.2 Mounting clearances
To guarantee a sufficient pressurisation of the modules, the following minimum
distances must be observed for the mounting of the CPX-E system
