Connecting the Power Supply Lines

Requisite Material
Equipotential Bonding
Connecting the Power Supply Cable
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.
The gas analyzer has a connection marked with the symbol
connecting line to the equipotential bonding on the building side. The
max. capacity of terminals is 4 mm
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
analyzer 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
connected.
Do not feed in the sample gas until the gas analyzer has reached room
temperature and the warm-up phase (see page 94) has ended!
Otherwise, the sample gas could condense in the cold analyzer.
