Climate class
DIN EN 60068-2-38 (test Z/AD)
Altitude according to
IEC61010-1 Ed.3
• Generally up to 2 000 m (6 600 ft) above MSL.
• Above 2 000 m (6 600 ft) if the following conditions are met:
– Ordering feature 020 "Power supply; Output" = A, B, C, E or G (2-wire versions)
– Supply voltage U < 35 V
– Supply voltage of overvoltage category 1
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)

– IP66, NEMA4X
• With open housing: IP20, NEMA1
• Display module: IP22, NEMA2
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.

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 ε
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
6) 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").
