AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B 125
Fidas24: Power supply line connection
CAUTION
The gas analyzer and the analyzer module must be de-energized before
the connector of the 115/230 V AC power supply for heating the detector
and the heated sample gas connection is connected or disconnected.
Otherwise the heating may be damaged.
115/230-V-AC connecting cable
A connecting cable is supplied for the 115/230 V AC power supply for heating
the detector and, if applicable, the heated sample gas connection (length
5 m, cable cross-section 3 x 1.5 mm
2
) with a 4-pole socket connector for the
connection to the analyzer module.

The illustration shows the pin side of the plug 30 in the analyzer module (see
page 83).
The operating voltage of the detector heating is automatically detected and
switched. The set voltage can be identified through two LEDs on the mains
distribution card.
115/230 V AC connection to the analyzer module
1 Ensure that the power supply feeder has an adequately dimensioned
protective device (circuit-breaker).
2 Install an easily accessible mains isolator in the power supply feeder
near the gas analyzer, or a switched socket-outlet, in order to be able to
completely disconnect the heating of the detector and the heated sam-
ple gas connection from the power supply if required. Mark the mains
isolator in such a way that the assignment of the devices to be discon-
nected can be clearly recognized.
3 Make sure that the gas analyzer and the analyzer module are
de-energized.
4 Attach the supplied 115/230-V-AC connecting cable with the 4-pole
socket connector to the power supply connection 30 of the analyzer
module and screw tight.
5 Connect the wires on the free end of the power cable to the power sup-
ply.
