– Make sure that the oil content remains constant during the entire service
life of the product.
– Never change from oiled to oil-free compressed air.
• Only operate the product with a voltage source and control voltage suitable
for PELV. The voltage source must ensure secure electrical isolation of the op-
erating voltage from the mains in accordance with IEC / EN 60204-1 (accident
prevention).
• Never ground the 24 V side of the supply voltage.
• The product causes high-frequency interference. If there are any sensitive de-
vices in the vicinity of the product, take appropriate interference suppression
measures.
Ambient conditions
• Let the product acclimatize for a few hours before installation. Otherwise wa-
ter may condense in the housing.
• Keep the installation location free from vibration.
• Protect the product from direct sunlight and UV radiation.
• Avoid increased output pressure tolerances: Make sure that high-frequency
radiation from interference-emitting devices is kept away from the product.
6.2.2 Required accessories, materials and tools
Select material and tools that are suitable for your product configuration. De-
pending on the configuration, you will need further accessories.
Mounting material
Assembly requires the following material, which is not included in the scope of
delivery. Respect dimensions and tightening torques.
• 2x screws
• 2x seals
• 1x silencer
• 1x screw for ground
• 2x tooth lock washer for ground
Tools
• No special tools required.
Accessory parts
• Only use accessories approved by the manufacturer. See g 14. Accessories.
6.3 Preparation
6.3.1 Unpacking and checking the product
1. Check the material number to see if the product matches your order.
2. Check the product for transport and storage damage.
Do not install a damaged product. Return damaged products together with
the delivery documents. See
3. Prepare required accessories, materials and tools.
6.3.2 Notes
• Insulate the wire ends against each other (material protection).
• Make sure that the power supply plug is protected against contamination
with a suitable sealing cap until assembly (material protection).
• Make sure that the pneumatic connections are protected against contamina-
tion with a suitable blanking plug until assembly (material protection).
6.3.3 Implementing safety measures
Procedure
1. Do not carry out any work on the system during preparation.
2. Close off dangerous areas.
3. Make sure the system or system part is not under pressure or voltage.
4. Protect the system against being restarted.
5. Allow the product and adjacent system parts to cool down.
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.

g 4.3 Returning the
product.
After parameterization, download and install the product-specific parameteri-
u
zation software if required.
6.4 Mounting the product
Insert the screw in the through hole in the housing and tighten. See g Fig. 1.

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).
INFO: Depending on the silencer used, the exhaust time may be longer.
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
The connection is made via a 5-pin M12x5 round plug. See
with 5-pin M12
plug.
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.
• Cable cross-section of supply voltage: min. 0.50 mm².
In case of long supply lines, select a larger cable cross-section if required.
• 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
