DVWG, Ex, GL, etc. as well as VDE and local
EVUs.
The instrument must be decommissioned and
secured against inadvertent re-operation if a situa-
tion arises in which it must be assumed that safe
operation is no longer possible. Reasons for this
assumption could be:

evident damage to the instrument

failure of the electrical circuits

long storage in temperatures over 85°C

considerable strain due to transport
Repairs may be carried out by the manufacturer
only.
A professional single conformity inspection as per
DIN EN 61010, section 1, must be carried out
before the instrument can be re-commissioned.
This inspection must be performed at the manufac-
turer's location. Correct transport and storage of the
instrument are required.

instrument by the customer are not permitted. This
also applies to replacement parts. Any modifica-
tions/alterations required will be carried out by
Fischer Mess- und Regeltechnik GmbH only.
1.6 Impermissible modes of operation
The operational safety of this instrument can only
be guaranteed if it is used as intended. The instru-
ment model must be suitable for the medium used
in the system. The limit values given in the technical
data may not be exceeded.
1.7 Safe working practices for mainte-
nance and installation work
