4.1 Installation
Note
Material damage due to incorrect mounting
Select screws that are suitable for the material of the interlinking block:
– plastic: thread-cutting tapping screws
– Metal: Screws with metric thread.
When ordering a single module, all required screws are supplied.
1. Check seal and sealing surfaces. Replace damaged parts.
2. Push the module carefully and without tilting into the interlinking block up to the
stop.
3. Turn the screws into the existing thread.
4. Tighten the screws in diagonally opposite sequence. Tightening
torque:1 Nm ± 10 %.
4.2 Dismantling
1. Unscrew screws.
2. Pull the module without tilting out of the interlinking block.

Power supply
The operating and load voltage supply is fed in via interlinking blocks or end plates
(
è
CPX system description P.BE-CPX-SYS-…).
Warning
Electric voltage
Injury caused by electric shock, damage to machine and to system
For the electrical power supply, only use PELV circuits in accordance with
IEC 60204-1/EN 60204-1.
Use only voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204-1/EN 60204-1.
Observe the requirements of IEC 60204-1/EN 60204-1 for PELV circuits.
Always connect all circuits for operating and load voltage supply U
EL/SEN
, U
VAL
and U
OUT
.

(Factory setting)
Remote I/O
All functions of the CPX terminal are controlled directly by
the higher-order controller. A control block integrated into
the CPX terminal (e.g. CPX-CEC or CPX-FEC) works as a
passive function module without controller.
DIL 1.1: ON
Remote controller
A control block integrated into the CPX terminal
(e.g. B. CPX-CEC or CPX-FEC) takes over I/O control. This
operating mode is only useful if a control block is integ
rated into the CPX terminal.

The type of addressing or the host ID of the IP address of the
bus node is set via DIL switch elements 3.1 ... 3.8.
Possible settings:

Ensuring the degree of protection
Note
Short circuit
Malfunction or damage to the electronics
Use connection technology with the required degree of protection e.g. plug
NECU-M-S-D12G4-C2-ET (
è
www.festo.com/catalogue).
Use cover caps to seal unused connections, e.g. cover cap ISK-M12
(
è
www.festo.com/catalogue).
Mount the DIL switch cover:
Check seal, place cover and push it down, tighten screws. Tightening torque
maximum 0.4 Nm.
