Installation and commissioning

6.1

Assembly

The installation location must be easily accessible and free from vibration. The
permissible ambient temperatures (see Chapter 5, page 117 for further information)
may not be exceeded. Protect the transmitter from heat radiation, rapid temperature
fluctuations, heavy soiling and mechanical damage.
The desired operating data must be compared with the values specified on the
device's rating plate before installation.
The housing may only be opened to alter the hardware settings.
A distance of about 5 mm away from adjacent devices is recommended for better
heat dissipation.
If more than one device is running in a cabinet read the notes and recommendations
indicated on page 119 in the footnotes.
WARNING
It is not permitted to modify or add to the devices!
6.2

Installation and removal

The transmitter can be fixed either to a 35 mm DIN rail (DIN EN 5022) or a 32 mm
G-rail (DIN EN 50035). The device is removed from the rail as shown in (figure 3,
page 84). The fastening element for the transmitter (DIN rail adapter) is removable
(3, figure 3). After pressing the catch (4, figure 3) the fastening element can be
pushed sideways out of its guide. It can be pushed into either the top or bottom guide
on the housing. The release catch (5, figure 3) must be at the bottom or top edge of
the housing.
The transmitter may only be installed in closed operation rooms, housings and
cabinets.
Field housings or switch cabinets must be used to install transmitters in the field. The
size, type of protection and material must be adapted to the respective requirements.
The ambient conditions specified in the technical data (Chapter 5, page 117) must
be observed.
