102 EL3000 CONTINUOUS GAS ANALYZERS | CI/EL3000-EN REV. B
Connecting the power supply lines
Requisite material
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.
Equipotential bonding
The gas analyzer has a connection marked with the symbol for the con-
necting line to the equipotential bonding on the building side. The max.
capacity of terminals is 4 mm
2
.
Connecting the power supply cable
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
disconnect all the power from the gas analyzer if required. Mark the
mains isolator in such a way that the assignment of the devices to be
disconnected can be clearly recognized.
3 Attach the mains lead to the power supply connection of the gas ana-
lyzer and fasten the connector by means of the bracket.
4 Connect the other end of the mains lead to the power supply.
5 Connect the gas analyzer to the equipotential bonding on the building
side if this is required by the relevant installation regulations.
NOTES
The gas analyzer can be started up after the power supply has been con-
nected.
Do not feed in the sample gas until the gas analyzer has reached room tem-
perature and the warm-up phase (see page 106) has ended! Otherwise, the
sample gas could condense in the cold analyzer.
