To avoid interferences a separate shielding must be provided for analog and digital control
lines. Depending on the use of the relay outputs, an extra shielding is to be used, too.
In case of inductive load on the relay outputs a protective wiring must be provided (e.g.
free-wheeling diode)!
The terminals of the control terminal strip and the transmitter inputs are securely isolated
in accordance with EN 50178.
*) Connect potential equalizing line only if a
potential difference of >30 V exists between
the controls. The internal resistance is red-
uced to 30 kΩ.
