7 Assembly
Hazardous movements due to incorrect fastening!
Other system parts may be damaged by uncontrolled device movements.
O Make sure that the device is securely fastened.
O Always fasten the ED02 pressure regulator
– with screws in the through holes or
– with mounting kits (see "Accessories" in chapter 15) to a rail or an mounting
plate.
Malfunction caused by closed housing ventilation port!
If the housing ventilation port is closed, there is no atmospheric equalization and
the characteristics curve will change.
O Before installation, ensure that the housing ventilation port (
not, for example, painted shut.
O Ensure that the air can circulate freely through the housing ventilation
port ( –5).

You can assemble the ED02 pressure regulator in three different ways:
1. To a mounting plate using screws in the through holes,
2. Using the mounting kit for assembly on a mounting plate (R414002582),
3. Using the rail mounting kit for TH35-7.5 rails (R414002583).
Up to four devices can be linked pneumatically with each mounting type.
Before assembly
O Make sure the relevant system part is not under voltage or pressure.
O Let the ED02 pressure regulator acclimate itself for several hours before
installation, otherwise water may condense in the housing.
Installation conditions
Malfunction due to atmosphere containing oil!
Oil may clog the housing ventilation port. This will change the characteristic curve.
O Never operate the device in an atmosphere containing oil.
Mounting orientation

±α = 0 ... 90°, ±β = 0 ... 90°
In dry, grease-free, and dust-free environments, other mounting orientations are
available on request.
Stacking devices

Pressure feedback in the entire used inlet channel!
Mutual interaction of valve functions is possible.
O Only link a maximum of four devices.
O If necessary, connect an additional supply line at the alternative inlet
connection (8).
O If necessary, decouple the devices.
Up to four devices can be linked pneumatically. To do this, you will need the
appropriate stacking kit, depending on the number of devices (see "Accessories"
in chapter 15).
The kit includes:
W
2 M5 cylinder screws, length depending on kit
W
2 M5 nuts DIN 934
W
O-rings, number depending on kit
1. Remove the unused blanking screws (WS 2.5) (9).
2. Insert the seal (O-ring) (10) between the linked supply connections as shown
in .

If you want to fasten the devices using mounting kits:
3. Slide the cylinder head screws (SW 4) included in the stacking kit into the through
holes (6) and tighten the nuts (WS 8).
Tightening torque: 6 Nm
If you want to fasten the devices using screws in the through holes:
4. Slide the cylinder head screws (SW 4) included in the stacking kit into the through
holes (6) and mounting plate (11) and tighten the nuts (WS 8) (see

Assembling on a mounting plate
Fastening with screws in the through holes
1. Make sure the blanking screw is inserted correctly.
2. Position the device on the assembly surface so the blanking plugs are on the side
of the mounting panel.
3. Slide the cylinder head screws (WS 4) into the through holes (6) and the mounting
plate (11).
Tightening torque: 6 Nm
Fastening with a mounting kit for mounting plate
A mounting kit R414002582 is needed to assemble the device on a mounting plate.
The mounting kit for the mounting plate contains:
W
2 mounting panels (12)
W
2 toothed lock washers (13)
W
2 cylinder head screws (WS 4) (14), tightening torque: 6 Nm
1. See the dimensional drawing for the hole spacing
2. Assemble the mounting kit for the mounting plate as shown in
The mounting panels (12) catch in the recesses and can thus be aligned in three
directions at right angles to the device.
3. Fasten a single device with two mounting panels or stacked devices with at least
four mounting panels to the mounting plate.
Assembling on a rail
To assemble the device on a rail, you will need the TH35-7.5 rail mounting kit
R414002583. The mounting kit includes:
W
1 mounting plate (15)
W
1 cylinder head screw (WS 4) (16), tightening torque: 1 Nm
1. Assemble the mounting kit as shown in
The mounting panel (15) catches in the recesses and can thus be aligned in three
directions at right angles to the device.
2. Fasten a single device with one mounting panel or stacked devices with at least
two mounting panels to the rail.
Connecting the pneumatics
Danger caused by escaping compressed air!
Device is operating under pressure. If the alternative inlet connection (8) is
opened, the blanking screw (9) may be forced out by the compressed air and
cause injuries or damage.
O Always use your personal protective clothing or safety glasses as the least.
O Only connect an additional supply pressure connection in a pressure-free
state.
O Never open the blanking screw while the device is in operation.
The inside diameter of the supply line must be at least 4 mm (6 mm with four
stacked devices) to attain the air flow rate stipulated in the specifications.
To avoid changing the dynamics of the ED02 pressure regulator,
we recommend using push-in fittings.
To connect push-in fittings, slide the tubing up to the stop in the push-in fitting and
gently tug to see if the tubing is tightly inserted.
Pressure regulators for positive pressure range
(e.g. 0 to 2 bar, 0 to 6 bar, 0 to 10 bar)
1. Connect the supply line at inlet connection 1 (1) or at the alternative inlet
connection (8).
You can increase the air flow rate in stacked devices by connecting
the supply line at inlet connection 1 (1) and at the alternative inlet
connection (8).
2. Close the unused inlet connection with a blanking screw (WS 2.5), if necessary.
Tightening torque: 1.2 Nm
3. Connect the outlet line at outlet connection 2 (2).
Pressure regulators for –1 to +1 bar
1. Connect the supply line at inlet connection 1 (1) or at the alternative inlet
).

connection (8).
2. Close the unused inlet connection with a blanking screw (WS 2.5), if necessary.
3. Connect the outlet line at outlet connection 2 (2).
4. Remove the silencer from exhaust 3 (3) and connect the vacuum line at vacuum
connection 3 (3).
