Installation of control wires
The screen of digital signal wires, which are not connected to terminals, has to be con-
nected to the screen bars to decrease the impedance of the screen.
The screen of digital signal wires, which are connected to terminals, has to be connected
with as big surface as possible to ground.
If the screen is grounded via a single wire, the noise discharge is getting worse by 70%.
For screen connection commercial cable clamps are suitable.
If unscreened signal wires are used, install only twisted pair wires.
