Climate class DIN EN 60068-2-38 (test Z/AD)
Geometric height according
to IEC61010-1 Ed.3 Up to 2 000 m (6 600 ft) above MSL.
Can be expanded to 3 000 m (9 800 ft) above MSL by application of an overvoltage protection, e.g. HAW562
or HAW569.
Degree of protection
• With closed housing tested according to:
– IP68, NEMA6P (24 h at 1.83 m under water surface)
– For plastic housing with transparent cover (display module): IP68 (24 h at 1.00 m under water
surface)
5)
– IP66, NEMA4X
• With open housing: IP20, NEMA1 (also ingress protection of the display)
Degree of protection IP68 NEMA6P applies for M12 PROFIBUS PA plugs only when the PROFIBUS
cable is plugged in and is also rated IP68 NEMA6P.
Vibration resistance DIN EN 60068-2-64 / IEC 68-2-64: 20 to 2 000 Hz, 1 (m/s 2 ) 2 /Hz
Cleaning the antenna The antenna can get contaminated, depending on the application. The emission and reception of microwaves
can thus eventually be hindered. The degree of contamination leading to an error depends on the medium
and the reflectivity, mainly determined by the dielectric constant
e
r
.
If the medium tends to cause contamination and deposits, cleaning on a regular basis is recommended. Care
has to be taken not to damage the antenna in the process of a mechanical or hose-down cleaning. The
material compatibility has to be considered if cleaning agents are used! The maximum permitted
temperature at the flange should not be exceeded.
5) This restriction is valid if the following options of the product structure have been selected at the same time: 030("Display, Operation") = C("SD02") or
E("SD03"); 040("Housing") = A("GT19").
