6. Wear PPE.
6.3.4 Software installation
Parameterization software is only required if the default parameterization has to
be changed due to installation in the system. The parameterization software is
available for download on the product page in the Emerson store.
After parameterization, download and install the product-specific parameteri-
u
zation software if required.
6.4 Mounting the product
Insert one screw each in the through holes in the housing and tighten. See
u
g Fig. 1.
Tightening torque: max. 25 Nm
6.5 Connecting the pneumatic system
The pneumatic flow direction is from connection 1 to 2.
Procedure
1. Place a suitable sealing ring under each screw connection. Only use imperial
screw connections.
WARNING! Only use connection seals that are not made of teflon or hemp.
2. Connect the supply line to the inlet connection (1).
3. Connect the outlet line to the outlet connection (2).
4. Use a suitable silencer at the exhaust (3).
5. Adapt the cross-section of the pneumatic lines to the nominal width of the
valve: The cross-section of the outlet line (2) must be greater than or equal to
that of the inlet line (1).
6.6 Connecting the electrical system
Depending on the configuration, one of the following plugs is used for connec-
tion:
• M12x5 round plug, 5-pin. See
• M16 plug, 7-pin.
See g 6.6.4 Connection with 7-pin M16
• M5 plug, 8-pin.
See g 6.6.5 Connection with 8-pin M12
6.6.1 Notes
• Overvoltage and ripple outside the tolerances can damage or destroy the
electronics (material protection).
• Supply via a diode bridge is not permitted.
• Recommended ballast fuse: T 2.0 A (material protection).
• When connection a relay (inductive load) to the pressure switch output: Use a
recovery diode or a varistor.
• Use shielded cables to protect against interference and electrostatic effects.
• Select the wire cross-section so that a voltage drop of < 2 V occurs at 2 A.
• Do not lay control lines parallel to high-voltage power lines or control lines of
servo motors etc.
• Not intended for connection to a DC distribution network.
• If the cross-section of the connection cable is too small or the connection ca-
ble is too long, the tolerances of the output pressure and the analog signals
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).

plug.
– 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. 3.
3. Insert the eyelet of the grounding cable between two tooth lock washers and
fasten it with a screw (M4).

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.
• A maximum current of 200 mA is possible at pin 5.
• The maximum current of the pressure switch is 200 mA / 4.8 W (PNP output).
The output is protected against short-circuits and overloads.
Procedure
Connect the product according to the pin assignment.
