AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B 121
Power supply line connection – Safety notes
ATTENTION
Follow all applicable national safety regulations for the installation and
operation of electrical devices as well as the following safety precautions.
The protective lead (ground) should be attached to the protective lead
connector before any other connection is made. The protective lead con-
nection is assured when the power cable supplied is used.
The gas analyzer can be hazardous if the protective lead is interrupted
inside or outside the gas analyzer or if the protective lead is disconnect-
ed.
Only fuses of the specified type and rated current should be used as re-
placements. Never use patched fuses. Do not short-circuit the fuse holder
contacts.
If the power supply fuse fails, some power supply switch components can
still carry current.
Never connect line voltage to a 24-VDC analyzer module input. This will
destroy the analyzer module electronics.
An easily accessible mains isolator must be installed near the gas analyzer
in order to be able to completely disconnect the latter from the power
supply. Mark the mains isolator in such a way that assignment to the de-
vices to be separated can be clearly identified.
ATTENTION
Fidas24: 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 discon-
nected. Otherwise the heating may be damaged.
