4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, return for calibration).
Permissible conditions at the place of storage:
Storage temperature: -25 ... +80 °C [-13 ... +176 °F]
■
Humidity: 35 ... 93 % relative humidity (non-condensing)
■
Avoid exposure to the following factors:
Proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Hazardous environments, flammable atmospheres
■
Store the process transmitter in its original packaging in a location that fulfils the condi-
tions listed above. If the original packaging is not available, then store the instrument
in a container that is similar to the original packaging, so that the instrument can't be
scratched and is protected against damage if dropped.
5. Commissioning, operation
The instrument may only be commissioned and operated by skilled personnel/skilled
electrical personnel.
Clean the instrument as described in chapter 12, before it is commissioned.

5.1.1 Requirements for mounting point
The display and operating unit of the process transmitter can be adapted to the installa-
tion site.
→ See chapter 2.2 "Description"
No hazardous environment/flammable atmosphere.
■
Mechanical vibration/mechanical shock within the permissible values,
■
see chapter 15 "Specifications".
Sufficient space for a safe electrical installation.
■
Operating elements can be accessed following the mounting.
■
Protect the instrument from heat sources (e.g. pipes or tanks). Do not expose the
■
instrument to direct solar irradiation while in operation!
The components of the instrument must not be provided with thermal insulation.
■
Observe the permissible medium and ambient temperatures. These are constituent
■
elements of the order confirmation.
