4.4 Mounting and connecting
4.4.1 Requirements for mounting:
The following are essential for mounting:
● Gas lines, sample lines, exhaust gas lines
● Power switch, line fuse, power cable
● Equipotential bonding cable
● Communications cable
CAUTION
Do not remove the dummy plug prior to startup
 Leave the dummy plugs on the gas inputs until you start up the chromatograph.

Check the correct functioning of the gas lines before you connect them to the
chromatograph!
CAUTION
Destruction of the thermal conductivity detectors

Only use the carrier gas specified in the device documentation! The thermal
conductivity detectors could be destroyed.
 Do not operate the thermal conductivity detectors with bridge voltages higher than
those specified in the application data. The bridge voltages must be optimized at
minimum values in order to guarantee a long service life for the thermal conductivity
detectors The maximum bridge power is 70 mW for helium.
Note
Increasing the detection limit
If you are satisfied with a shorter service life for a thermal conductivity detector, you can
increase the maximum bridge power to more than 70 mW for helium.
Before increasing the bridge power, please first contact Siemens AG servicing personnel.
