1) The valve must only be supplied with 24V DC ±10% and a max. ripple of 10% (no supply via diode bridge). Overvolt-
age or a ripple rate exceeding these tolerances can damage the electronics.
2) The max. current at the digital output is 200 mA/4.8W (PNP output). The output is protected against short circuit
and overload.
3) If a relay (inductive load) is connected to the pressure switch output, a freewheel diode or a varistor must be used.
4) A shielded cable must be used for protection against interference and EMC.
5) The valve housing must be connected to the ground potential with low resistance via the ground connection (ØM4).
The eyelet of the grounding cable must be inserted between two toothed washers and fastened with a screw (M4).
The tightening torque corresponding to the screw must be observed.
