3. Mounting and Installation
3.1 Transport
•
The devices must be transported in the container supplied.
•
Devices with nominal diameter 40 to 300 mm (DN 40 to 300) must not be
lifted at the transmitter housing (
compact version
) or at the connection
housing (
remote version
) when transporting (see Fig. 2). Use carrier slings
when transporting and put the slings around both process connections.
Avoid chains as these could damage the housing.
Warning!
The center of gravity of the entire measuring device might be higher than the
suspension points of the slings. Therefore, when hoisting, make sure that the
device does not unintentionally turn or slip, as there is the risk of injury if the
device falls.
3.2 Degree of Protection
IP66/67 (EN60529)
Caution!
The devices fulfill all the requirements for IP66/67, Type 4X enclosure.
Compliance with the following points is mandatory following installation in the
field or servicing in order to ensure that IP66/67, Type 4X enclosure protection
is maintained:
•
Housing gaskets must be clean and undamaged when inserted in the
gasket groove. The gaskets may need to be dried, cleaned or replaced.
•
All housing screws and screw caps must be firmly tightened.
•
The cables used for connection must be of the specified outside diameters.
•
Firmly tighten the cable entry (see Fig. 3).
•
The cables must loop down before they
enter the cable entries (“water trap”, Fig.
3). This arrangement prevents moisture
penetrating the entry. Always install the
measuring device in such a way that the
cable entries do not point up.
•
Replace all unused cable entries with
dummy plugs.
•
Do not remove the grommet from the
cable entry.
Temperature Ranges
•
The maximum allowable ambient and
process temperatures must be
observed (see 6.1.6).
•
Ensure both pipeline heat insulation and
mounting position conditions are met
(see 3.3).
