6 Mounting ED12 pressure regulator
The ED12 pressure regulator must always be fastened to a base plate
(single subbase or base plate for stacking assembly).
Fig. 2: Mounting the ED12 pressure regulator on the base plate
Before assembly
O Make sure the relevant system part is not under voltage or pressure.
O Let the ED12 pressure regulator acclimate itself for several hours before
installation, otherwise water may condense in the housing.
Risk due to incorrectly mounted device!
An incorrectly mounted device may result in uncontrolled movements that could
damage other system parts.
O Please ensure that the device is securely fastened to a base plate, which in
turn is secured to the machine or a mounting plate.
O Fasten the base plate in the control cabinet or onto a mounting plate.
Vertical mounting is preferable for the ED12 pressure regulator.

α = 0 ... 180°
β = 0 ... 180°
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 Ensure that the air can circulate freely through the housing ventilation port (6).
O Never operate the device in an atmosphere containing oil.
O Before installation, ensure that the housing
ventilation port (6) is open and not, for example,
painted shut.

1. Insert the base plate gasket (10) in the respective
10
slots on the bottom of the ED12.
2. Apply slight pressure to the base plate gasket.

Mounting the ED12 pressure regulator on the base plate
The base plate has a coding pin (33), which fits into the matching coding boring (8) of
the ED12 pressure regulator. Correct assembly is thus ensured.
1. Rotate the ED12 pressure regulator so that the
coding pin (33) and coding boring (8) and on the same
side and can engage.

2. Place the ED12 pressure regulator on the base plate.
While doing so, ensure that the base plate gasket
does not slip.

The base plate coding pin fits into with the coding
boring on the ED12 pressure regulator.
00122958
Some base plates have two coding pins. For this reason, there is a second
coding boring on the same side of the ED12 pressure regulator. There is no
risk of confusion.
Firmly screw the ED12 pressure regulator onto the base
plate
1. Insert the four M6x70 screws into the four holes as
shown in the figure and screw tight.
Tightening torque: 6 Nm
2. Recheck the perfect seat of the base plate gasket (10)
to ensure protection class IP65.
The base plate gasket must not protrude at the side.
