may increase. Avoid increased tolerances of the output pressure and the ana-
log signals:
– If the cable is longer than 2 m, ideally use a current signal (0 ... 20 mA or
4 ... 20 mA) for the set point and the analog inputs and outputs.
– Always use the set point ground as reference for all analog signals (set
point, analog inputs, analog outputs).
– Make sure that the analog ground outside the valve is not connected to
the supply ground.
6.6.2 Grounding
1. Connect the cable shield of the connection cable on the power supply side
with the ground.
2. Use the FE ground connection (Ø M4) to establish a low-impedance connec-
tion between the valve housing and the ground (FE). See g Fig. 2.
3. Insert the eyelet of the grounding cable between two tooth lock washers and
fasten it with a screw (M4).

6.6.3 Connection with 5-pin M12 plug
Notes
• Round plug M12x5 must comply with the requirements as per DIN 60079-15
for electrical connection. The product has been checked with plug item
no. 88100729.
• The maximum current of the pressure switch is 200 mA / 4.8 W (PNP output).
The output is protected against short-circuits and overloads.
