4.3 Mounting
Method 1 : The PF4 comes with two screws, two wall plugs and two rubber
washers. There are two screw depressions in the bottom part of the housing
(closed on delivery). Use the template delivered with the PF4 to drill the holes
in the wall and put in the wall plugs. Place a rubber washer under each screw
head. Put a screw in each depression and push through the bottom of the
depression.
Method 2 : The mounting kit AC5002 (not included) is needed for mounting on
a DIN top-hat rail (35 mm / 1 3/8"). The mounting kit consists of two clips, which
are fastened to the back of the housing with the screws supplied.

4.4 Differential Pressure Connection
Tubes with an internal diameter of 4 mm can be connected. The tubes must be fastened securely so that
they do not move or vibrate during operation. This would falsify the measurement.
Configuration of differential pressure connections:
+ : Positive pressure connection
- : Negative pressure connection
