3.3 USB interface X7
The USB interface enables external storage media to be connected using USB plug
type A.
Note
Malfunction due to undefined switching statuses of the electronics.
If a USB hard disk without its own power supply is used, the maximum permitted
current consumption can be exceeded, e.g. when the USB hard disk is running up.
Controller CECC-D and CECC-LK:
Use only storage media with current consumption

100 mA.
Controller CECC-S:
USB storage medium and encoder are supplied from a common power source.
Use USB storage medium and encoder whose total current consumption

500mA.
3.4 Ethernet interface X8
The Ethernet interface
1 è
Fig. 2 enables connection of a programming unit, PC
or operator unit to the controller.
The Ethernet interface is designed as an RJ45 socket.
3.5 Serial interfaces X12 and X13 (CECC-S)

3.6 Multiple interface X14 (CECC-S)
The controller CECC-S has a combined interface with the following connection
options:
– Encoder (ENC, RS422-based encoders only)
– RS422
– RS485
Simultaneous use of these connection options is not possible.
Configure and use only one of the three connection options with
CODESYS.

4 Power supply
Caution
Risk of injury due to electric shock
For the electric power supply, use only PELV circuits that ensure a reliable
electric disconnection from the mains network.
IEC60204-1/EN60204-1 to be screwed in.
Always connect all circuits for operating and load voltage supply.
Note
The product may only be supplied from a single power source that fulfils the require­
ments of energy-limited circuits in conformity with IEC/EN/UL/CSA 61010-1 or of
an energy-limited voltage source (limited power sourse, LPS) in conformity with
IEC/EN/UL/CSA60950-1 or IEC/EN/UL/CSA 62368-1 or of a class 2 circuit in con­
formity with NEC or CEC.
