Installation
5.1
Safety instructions
Please observe the valid regulations for installation in
the country in which the differential pressure sensor is
installed and operated, and the national regulations for
accident prevention. Please also observe any compa-
ny-internal regulations, such as work, operating and
safety regulations.
The technical specifications and limit values stated
must not be exceeded under any circumstances. In
particular, this applies to the specified ambient tem-
perature range and IP degree of protection.
If a higher IP protection class is required for a special
application, the differential pressure sensor must be
installed in an appropriate housing or in an appropriate
enclosure with the required IP degree of protection.
5.2
Siting location requirements
To ensure the correct function of the unit, the conditions
for the installation site of the unit specified in section 8
"Technical specifications" must be observed.
Electromagnetic interference
– Interfering electrical installations (high frequency)
should be avoided.
5.3
Installation procedure
There are generally several options for installing the dif-
ferential pressure sensor:
1. Installation on the frame of the enclosure or IT enclo-
sure using the bracket included.
2. Installation with the provided bracket on a system
chassis.
3. Installation on a top-hat rail using the bracket includ-
ed along with a spring clip.
5.3.1
Installation notes
The differential pressure sensor must be positioned so
that it is ventilated with an adequate amount of air and
the ventilation slots are not covered.
5.3.2
Installation with the provided bracket on
the enclosure frame
The provided bracket is used for installation on the frame
of an IT enclosure.
For installation on a TS IT enclosure, break off the pro-
truding lugs at the rear of the bracket.

Preparing the bracket for installation on a TS IT enclo-
sure
Place the differential pressure sensor on the bracket
from above.
Fig. 3:
Attaching the sensor to the bracket
Move the sensor sideways slightly on the bracket so
that it latches into place.

Latching the sensor into place on the bracket
Fasten the bracket, including differential pressure sen-
sor, at the desired position in the enclosure or the IT
enclosure by making a quarter-turn of the connector.
