and reliable transmitter to determine the
conductivity and resistance of fluid media.
Liquisys M CLM 223 F / 253 F is particularly
suitable for use in the following areas of
application:
•Chemicals
•Pharmaceuticals
•Food industry
•Drinking water treatment
•Condensate treatment
•Municipal sewage treatment plants
•Water conditioning
2.2 General safety notes
This device has been manufactured for safe
operation according to the state of the art in
engineering and conforms to the applicable
regulations and European standards (see
Technical data). It has been designed
according to EN 61010-1 and has left the

regard to safety aspects.
However, if used imporperly or for purposes
other than the intended purpose, it may be
dangerous, e.g. due to incorrect connection.
Warning:
•Operating this instrument in any
way other than as described in
these instructions may com-
promise the safety and function of
the measuring system and is
therefore impermissible.
•The notes and warnings in these
installation and operating instruc-
tions must be strictly adhered to!
2.3 Installation, start-up, operation
Warning:
•This device may only be installed,
connected electrically, commis-
sioned, operated and serviced by
properly trained personnel
authorized by the system operator.
•The personnel must be familiar
with these operating instructions
and must adhere to the
instructions described therein.
•Make sure that the power supply
ratings match the data specified
on the nameplate before you
connect the instrument to a power
source.
•A clearly identified mains discon-
necting device must be installed
close to the instrument.
•Live components can be touched
through the vent slots in the
housing and the openings on the
rear of the housing. Do not insert
any tools, wires or similar into
these slots (only CLM 223).
•Check that all connections have
been properly made before
powering up the system!
•Damaged equipment that may be
dangerous must not be operated
and should be clearly identified as
being defective.
•Measuring point faults may only
be repaired by authorised and
trained personnel.
•If faults cannot be remedied, the
instrument must be removed from
service and secured to prevent
accidental start-up.
•Repairs not described in these
