•The power supply module must only be installed in areas that are only accessible
to service engineers.
• The power supply module is not permitted to be used in potentially explosive at-
mospheres (EX zone).
• It is imperative that the power supply module is enabled prior to commencing in-
stallation and maintenance work:
– Disconnect the supply voltage before working on the voltage supply or on the
incoming cable.
– Pull out the power plug.
– Switch off the associated fuse if permanently connected.
• Connections and changes may only be carried out by trained electrical specialists.
• It is not possible to guarantee sufficient cooling of contact and fire protection due to
the compact design. For this reason, fire protection is to be ensured by means of
the environment of the power supply installed, e.g. through installation in a control
cabinet which complies with fire safety regulations.
• Adhere to national regulations and guidelines in the respective country of use (in-
stallation, preventive measures, EMC, etc.).

3.1 MOVI‑PLC® I/O system C
MOVI-PLC®
I/O system
C
The MOVI-PLC® I/O system C is an automation system with a modular structure for
installation on a 35 mm mounting rail.
The modular MOVI-PLC® I/O system C extends the interfaces of the MOVI-PLC® con-
troller.
A MOVI-PLC® I/O system C contains a bus coupler (CAN bus coupler or EtherCAT®
bus coupler) to which up to 64 I/O modules can be connected via the backplane bus.
The bus couplers communicate with the MOVI‑PLC® controller via system buses. Up
to 64 MOVI-PLC® I/O systems can be connected depending on the controller type.
This means the MOVI-PLC® controller can automatically access a large number of in-
puts and outputs.
You can adapt this system precisely to your automation tasks using the 2, 4 and 8-
channel peripheral modules. The DC 24 V voltage supply is integrated in the back-
plane bus. This means that you can exchange defective electronics modules when the
wiring is upright. You can define further potential areas inside the system for the DC
24 V voltage supply using the differently colored power supply modules.

The base module serves as the holder for the electronics module and contains the fol-
lowing components:
• Backplane bus with voltage supply for the electronics [2]
• Connection to the DC 24 V voltage supply [3]
• Staircase-shaped terminal block for the wiring [4]
• Locking lever for attaching the module to a mounting rail [1]
With this locking system, you can set up your MOVI-PLC® I/O system C outside of
your control cabinet and subsequently install it in the control cabinet as a complete
system. For installation and disassembly, lift up the locking lever until it audibly locks
in place.

The functionality of a peripheral module is defined via the electronics module. The
electronics module is connected to the base module by a secure sliding mechanism.
In the event of an error, you can exchange the defective electronics module for a fully
functional module. The wiring is not changed by this. Only modules, which may be
combined, can be installed via an integrated factory coding of the electronics modules.
Status LEDs for the status display are located on the front. For easy wiring you can
find appropriate wiring diagrams on the side of each electronics module.

Power supply modules provide the voltage supply in the MOVI-PLC® I/O system C.
These are either integrated in the bus coupler or they can be installed between the pe-
ripheral modules. You can define potential groups of the DC 24 V voltage supply for
each power supply module. The power supply modules are of a different color to the
peripheral modules so they can be identified more easily.

3.2.4 Shield bus carrier
12865183627
The shield bus carrier is used to pick up shield buses (10 mm x 3 mm) for the connec-
tion of cable shields.
The shield bus carrier is connected to the base module below the terminal block. You
must remove the spacer on the shield bus carrier for flat mounting rails.
Shield bus carrier, shield bus and cable shield fastening parts are not included in the
scope of delivery. They are only available as accessories.
3.2.5 Bus cover
12865186315
A bus cover is included in the scope of delivery for each bus coupler in order to protect
the bus contacts. You must remove the bus cover on the bus coupler prior to installa-
tion. Always install the bus cover on the outermost module in order to protect the bus
contacts.
