… Connecting the power supply 
 
Grid connection cable Fidas24 
A connection cable is provided for the power supply 
(115 / 230 V AC) for heating the detector and, if necessary, the 
heated sample gas connection (length 5 m, cable cross-section 
3 × 1.5 mm
2
) with a 4-pole socket connector for the connection 
to the analyzer module. 
 
 
Figure 47:  Pin side of the plug 30 
 
The illustration shows the pin side of the plug 30 on the analyzer 
(see Figure 32 on page 80). 
 
The operating voltage of the detector heating is automatically 
detected and switched. The set voltage can be identified 
through two LEDs on the mains distribution card. 
 
 
 
 
Connect power supply lines 
1.  Ensure that the power supply feeder has an adequately 
dimensioned protective device (circuit-breaker). 
2.  Install an easily accessible mains isolator or a switched 
socket in the power supply line, close to the gas analyzer, so 
that all the poles of the gas analyzer can be disconnected 
from the power supply if necessary. Label the supply circuit 
isolator to make it clear that it is associated with the device 
that needs to be isolated. 
3.  Plug the cold device power cable into the power supply 
connection X01 (see Figure 38 on page 90 and Figure 39 on 
page 91) of the gas analyzer and fasten the plug with the 
bracket. 
4.  Attach the Fidas24 power cable to the power supply 
connection 30 (see Figure 32 on page 80 and Figure 33 on 
page 81) of the Fidas24 analyzer module and tighten. 
5.  Connect the other ends of the power cable to the power 
supply. 
6.  If stipulated by the relevant installation regulations, connect 
the gas analyzer to the building’s equipotential grounding 
system. 
 
Note 
The supply circuit isolator must mutually isolate the power 
supply of the gas analyzer and the Fidas24. 
 
Note 
The gas analyzer can be put into operation as soon as it is 
connected to the power supply of the building.
