2 Safety instructions
2.1 Intended application
The Liquisys M COM 223 F / 253 F is a
reliable, field-tested transmitter for measuring
the oxygen content of fluidmedia.
The Liquisys M COM 223 F / 253 F is
particularly suitable for use in the following
areas of application:
•Process control in enzyme production
•Control of culture preparations
•Biotechnological production
2.2 General safety instructions
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

ratings match the data specified on
the nameplate before you connect
the instrument to a power source.
•A clearly identified mains
disconnecting 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 slits (only COM 223 F).
•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.
•Any troubleshooting of the
measuring point is to be
performed exclusively by
authorized, trained personnel.
•If faults cannot be remedied, the
instrument must be removed from
service and secured to prevent
accidental start-up.
