8.1 Grounding
The device must be grounded to protective earth (PE) via the blade terminal provided. In
addition, ensure that when installing into the control cabinet, a large grounding surface is
provided. It is important to establish a low-Ohm connection to ground to ensure error-free
function. The ground connection must be made with the maximum wire cross-section and
largest (electrical) surface possible. The cable length of the ground connection must also
be kept as short as possible.
8.2 Shielding
For Ethernet, CAT5e (STP - Shielded Twisted Pair) cables are recommended. The cable
shielding is connected to ground via the connector. Noise signals can then be prevented
from reaching the electronics and affecting the function.
