Operating instructions for the IP20 version
4.1
Installation / Fixing
The Sensor Profibus Module type 9221 has a snap-fit design for mounting on a
standard 35 mm DIN (top-hat) rail to DIN EN 50022. The unit is fixed to the DIN
rail via a clip on its rear side. First place the clip on the DIN rail from above and
then press the module down onto the DIN rail until the lower edge of the clip
snaps onto the DIN rail. For optimum measurement quality the DIN rail must be
grounded.
To remove the module, once again push down on the module from above while
tilting the lower edge of the clip forwards to release the module from the rail. The
module must only be installed by a qualified person.
4.2
Degree of protection
The Sensor Profibus Module type 9221 has IP20 degree of protection. This
means that the module is not protected against water ingress, but is protected
against ingress of solid particles of diameter > 12.5 mm.
4.3
Ambient temperature
The permitted ambient temperature range for the Sensor Profibus Module type
9221 during operation is 0 °C to +60 °C. The unit can be stored at temperatures
between -30 °C and +85 °C.
