124 AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B
Power supply line connection
Requisite material
The gas analyzer is supplied with a power cord and a separate two-prong
grounded plug. The power cord is 5 meters (16.4 feet) long and has a
three-prong grounded-instrument plug for connection to the power supply.
If the supplied mains lead is not used, select conductive material which is
appropriate for the length of the lines and the predictable current load.

Power supply line connection
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 gas analyzer from the power supply if re-
quired. Mark the mains isolator in such a way that the assignment of the
devices to be disconnected can be clearly recognized.
3 Connect the power cord supplied to the –X01 with grounded-instrument
connector on the power supply connector of the electronics module and
secure it with the clip.
4 Connect the other end of the power cord to the power source.
NOTE
The gas analyzer may start when the power supply is connected.
Connecting equipotential bonding
The electronics module and the analyzer modules have a potential compen-
sation connector designated by the symbol . The connection has an M5
female thread for screwing in suitable screws or terminals.
Use this connection to link each module to the building’s potential compen-
sator in accordance with local regulations.
