4. Transport, packaging and storage
4.1 Transport
Check the pressure switch for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
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, sending for
repair).
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +70 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)
5. Commissioning, operation
5.1 Check the instrument
Prior to commissioning, the pressure switch must be subjected to a visual inspection.
■
Leaking fluid is indicative of damage.
■
Only use the pressure switch if it is in perfect condition with respect to safety.
5.2 Requirements for mounting point
The mounting point must meet the following conditions:
■
Protected from weather influences.
■
Permanent exposure to UV light/sunlight can lead to a change in the colour of the plastic parts and a clouding/
yellowing of the status displays. Therefore, a possible limitation of the visibility of the status displays cannot be
excluded. However, this has no effect on the functionality of the instrument.
■
Under corrosive environmental conditions (such as salty, humid air), reductions in the gloss level of the metallic
surfaces, or even corrosion on the instrument, may occur, which make readability of the product label more difficult.
However, this has no effect on the functionality of the instrument.
■
Sealing faces are clean and undamaged.
■
Sufficient space for a safe electrical installation.
