With devices with explosion protection type EEx dem [ia]
(7ME5033-**D** and 7ME5033-**G**), the cover of the terminal box for
auxiliary power and process outputs may also be opened when live for
testing purposes. The cover over the terminals for the auxiliary power
(terminals 1 and 2) may not be removed. Only certified testing devices
may be used for testing.
The allocation of the temperature classes takes place depending on
media and ambient temperature and the nominal size:
Remote version:
Ambient temperature -20 to +60 _ C: Temperature class T6
Compact version:
When nothing else is specified,an upper temperature limit of the
measuring medium of +90
_ C (values in brackets) always applies for
measurement sensors with a vulcanized rubber lining.

The measurement sensors can be used in zone 1. An explosive mix
under atmospheric conditions (pressure: 0.8 to 1.1 bar; temperature:
-20 to +60
_ C) may only occur in the measuring tube for a short period
of time, e.g. when filling and emptying.
The measuring tube should be filled exclusively with media to which the
seal and lining materials are chemically resistant (see order description
of the measurement sensor). Only conductive media are permissible
(minimum conductivity: 3
μ S/cm).
