7.3 Link
Hanging the linking element into place
1. Place the linking element into the
correct position on the H-rail.
2. Clip the linking element to the H-rail.
3. Push together the linking elements
until they engage.

Installation
Note
Malfunction due to electromagnetic interference.
Connect screening to the connection for functional earth FE.
Connect the H-rail to the earth potential with low impedance.
8.1 Power supply concept
A CPX-E system uses separate voltages to supply the electronic and sensors (U
EL/
SEN
) and to supply outputs (U
OUT
). The voltage potentials (+24 V DC and 0 V DC)
are respectively connected to each other in the terminal strips. It respective
voltage can be conducted from one module to another.
Warning
Risk of injury due to uncontrolled movements of the connected actuators.
A feedback loop through the sensor and/or actuator supply of the modules can
supply the CPX-E system and lead to unwanted functions.
Keep the range of movement of the connected actuators unobstructed.
Operating voltage supply U
EL/SEN
The operating voltage supply U
EL/SEN
to supply the electronics and sensors is fed
at the bus module or controller and distributed internally to the entire CPX-E
system though the link.
Load voltage supply U
OUT
The load voltage supply U
OUT
to supply the outputs is fed separately directly at
every module with outputs.

Fig. 12
The operating voltage supply U
EL/SEN
and load voltage supply U
OUT
are
implemented separately from each other within the CPX-E system.
If this separation is not required for the respective use case, both voltages
can also be supplied from a common voltage source. In this case, the load
voltage supply must be able to be disconnected separately.

Warning
Electric voltage
Injury caused by electric shock, damage to machine and to system
For the electrical power supply, use only PELV circuits in accordance with
IEC 60204-1/EN 60204-1 (Protective Extra-Low Voltage, PELV).
Observe the general requirements IEC 60204-1/EN 60204-1 of the PELV
power circuits.
Use only voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204-1/EN 60204-1.
Always connect all circuits for the operating and load voltage supplies U
EL/SEN
and U
OUT
.
1. Make sure the module and line are
de-energised.
2. Strip the end of the line and fit wire
end sleeves if required.
3. Disengage the spring-loaded ter
minal interlock (e.g., with a slotted
screwdriver).
4. Insert the end of the line into the ter
minal strip to the limit stop.
5. Engage the spring-loaded terminal
interlock.
