Electrical Line Connection, continued
Step Action
Make sure the voltage shown on the rating plate matches the
line voltage.
1
The operating voltage cannot be switched over.
2 Make sure the power supply leads have an adequately dimensioned
protective device (breaker).
3 Install a switched outlet or a breaker in the power supply wiring near
the sample gas cooler. This should allow the sample gas cooler and
all switches to be completely disconnected from the power supply if
necessary. The disconnection device should be identified in such a
way that its relationship to the equipment that it is designed to
disconnect can be clearly seen.
Connect the power supply wiring to the power supply.

The sample gas cooler may start when the power supply is
connected.
Power Supply Activation, Lead Time
WARNING!
Before activating the power supply check once again that the operating
voltage setting matches the line voltage (see rating plate)
The sample gas flow should only be started after the lead time period.
Power Supply
Activation
Activate the power supply using the externally installed breaker or the switched
outlet.
The peristaltic pumps start to run (counterclockwise).
Lead Time The lead time is approx. 15 minutes. This allows the sample gas outlet tempera-
ture of +3 °C, which is set in the factory, to be reached.
Status Signal During the lead time the monitor will output the temperature alarm signal.
Readiness At the end of the lead time period the sample gas cooler is ready for operation.
Sample Gas Supply The sample gas must not be switched on until the sample gas outlet temperature
lies within the limit values set in the factory, i.e. when it has fallen below +6 °C.
