Mechanical Installation
4.1 General
The PF4 can be mounted on a wall or on a DIN top-hat rail. The position of the device and thus of the differential
pressure sensor has no influence on measurement, i.e. the device is not sensitive to position. However, for
exact measurement, the device must not move and must not be exposed to vibrations.
IMPORTANT:
After complete mechanical installation, the atmospheric pressure must be programmed in the device as
described in chapter 6.1.1.
4.2 Housing
The housing can be opened by unscrewing four screws. The screw breakthroughs for wall mounting and
electrical connections for the power supply, analog outputs, service interface and the relay are to be found inside
the housing.
