3.3.2. Grounding
On the base plate of the device (see "3.1.1. Top view", pos. 10a)
there is a threaded bolt of dimensions M4 x 15 mm with two
nuts for connecting the grounding wire with the frame ground.

For reasons of operational safety, the 0V potential of the KUAX
680C has a capacitive connection to the frame ground. High-fre-
quency interferences can bleed off via this connection.

The connector casings of interfaces RS 232/1 and RS 232/2 and
the "Shield" connectors of the RS 485 interface are directly
connectrd to the frame ground. We recommend using these po-
sitions for connecting the shields of the data lines. Possible in-
terference signals can thus bleed off without causing any dam-
age.
Connect the basic device to ground via the grounding pin to
render these measures effective. Always choose the shortest pos-
sible connection.
