Connecting the computer unit-control unit connecting cable
Introduction
For data exchange, connect the control unit and the computer unit with the connecting cable
which is illustrated in the "Options" section.
Warning
Avoid contact with network lines and data transmission lines during thunderstorms and do
not disconnect any lines during this time.
For complete isolation from the power supply, always pull out the power plug.
Procedure
1. Plug the jack plug of the connection cable into the connector on the remote module of the
control unit, as illustrated in the section "Connecting a decentralized design."
2. Lock the jack plug.
3. Screw on the cable strain relief.
4. Plug the male connector of the connection cable into the connector on the host module of
the computer unit, as illustrated in the chapter "Description," "Connecting a decentralized
design."
5. Screw on the cable strain relief.

Connecting the power supply.
Principle
Warning
Select an adequately large cable diameter so that the device is not damaged by the cable
during a short circuit.
Power supply AC 110/230 V
The device can be operated in AC 110/230 V networks. The voltage is switched
automatically.
DC 24 V power supply
Caution
Connect the device with DC power supply only to 24V power supply networks which comply
with the requirements of a secure low voltage SELV.
