4.5.1 Connecting cables
The connections are located at the rear side of the Panel PC behind a cover and are documented in the
chapter
When connecting cables to the Panel PC, please adhere to the following order:
•
Disconnect the Panel PC from the power supply.

Connect all cables at the Panel PC and at the devices to be connected.
•
Ensure that all screw connections between connectors and sockets are tight!

4.5.2 Earthing measures
Earthing connections dissipate interference from external power supply cables, signal cables or cables to
peripheral equipment. Establish a low-impedance connection from the earthing point on the Panel PC
housing (see chapter
) to the central earthing point on the control cabinet wall, in
which the computer is being installed.
Malfunction possible with missing ground connection
