11 Wiring Guidelines
11.1 Ground
To ensure that the display unit functions error-free, the blade terminal on the back panel
must be connected to the earth bus. It is important to create a low-ohm ground connection,
only then can error-free operation be guaranteed. The earth connection should have a
maximum cross section and the larges (electrical) surface possible.
11.2 Shielding
For the Ethernet, CAT5 cables with shielded RJ45 connectors must be used. The shielding
on the CAT5 cable is connected to ground over the RJ45 plug connector. Noise signals can
therefore be prevented from reaching the electronics and affecting the function.
