plugs) 

 Micro-porous filter (see page 67) (pre-assembled)

tools and technical documentation 

 CD-ROM "Spare parts analytical" with information on spare parts 

 Instructions in brief for Installation, Commissioning and Operation

Fidas24:

 Mains lead, length 5 m, with 4-pin socket connector and separate 

grounding connector for the power supply to the heating of the 

detector and the heated sample gas connection 

 Accessories pack with fittings and O-rings for connection of the 

sample gas line 

 Exhaust pipe with fitting nut and compression fitting

Material Required for the Installation (not supplied) 

Gas Connections 

 For the connection of pipelines: Threaded connections with a 1/8 NPT 

thread and PTFE sealing tape 

Fidas24: Use only metal threaded connectors! 

Fidas24: Gas lines 

Process gases, test gases and waste air 

 PTFE or stainless steel tubes with 4 mm inside diameter and 

PTFE or stainless steel tube with at least 10 mm inside diameter for 

waste air 

 Tube fittings 

 Pressure regulator 

 Flow restrictor in the combustion gas supply line (see page 30) 

 Shut-off valve in the combustion gas supply line (see page 30) 

Sample gas 

 Heated sample gas line (recommended: TBL 01) or 

unheated sample gas line (PTFE or stainless steel tube with 

inside/outside diameter 4/6 mm). 

The fittings and O-rings required for the connection are included in 

the scope of supply and delivery of the gas analyzer. 

Flowmeter/Flow Monitor 

 Flowmeter or flow monitor with a needle valve for adjustment and 

monitoring of the sample gas flow rate and purge gas flow rate if 

required 

 Notes for the selection and use of flowmeters: 

 Measuring range 7…70 l/h 

 Pressure drop < 4 hPa 

 Needle valve open 

Recommendation: Flowmeter 7…70 l/h, Part Number 23151-5-

8018474 

Shut-off Valve 

 Install a shut-off valve in the sample gas line (definitely recommended 

with pressurized sample gas). 

Purging of the gas line system 

 Provide a means for purging the gas line system by feeding in an 

inert gas, e.g. nitrogen, from the gas sampling point. 

Installation Material 

19-inch Case (Model EL3020) 

 4 oval head screws (Recommendation: M6; this depends on the 

cabinet/rack system) 

 1 pair of mounting rails (Design depends on the cabinet/rack system), 

length approx. 240 mm corresponding to approx. 2/3 of the case 

depth 

Wall-mounting Case (Model EL3040) 

 4 screws M8 or M10 

Signal Lines 

 Select conductive material which is appropriate for the length of the 

lines and the predictable current load. 

 Notes concerning the cable cross-section for connection of the 

I/O modules: 

 The max. capacity of terminals for stranded wire and solid wire is 

1 mm2

 (17 AWG). 

 The stranded wire can be tinned on the tip or twisted to simplify 

the assembly. 

 When using wire end ferrules, the total cross-section may not be 

more than 1 mm2

, i.e. the cross-section of the stranded wire may 

not be more than 0.5 mm2

. The PZ 6/5 crimping tool of 

Weidmüller & Co. must be used for crimping the ferrules. 

 Max. length of the RS485 leads 1200 m (max. transmission rate 

19200 bit/s). Cable type: 3-core twisted-pair cable, cable crosssection 0.25 mm2

 (e.g. Thomas & Betts, Type LiYCY). 

 Max. length of the RS232 leads 15 m. 

Power Supply Lines 

 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. 

 Provide a mains isolator or a switched socket-outlet, in order to be 

able to disconnect all the power from the gas analyzer if required. 

Requirements for the Installation Site, Power Supply 

NOTE 

For the analyzers ZO23 and Fidas24 the information contained in the 

sections "ZO23: Preparation for Installation" (see page 25) or "Fidas24: 

Preparation for Installation (see page 30)" must be considered in addition. 

Requirements for the Installation Site 

The gas analyzer is only intended for installation indoors. 

The max. altitude of the installation site may not exceed 2000 m above 

sea level. 

The installation site must be stable enough to bear the weight of the gas 

analyzer! 

To ensure safe installation and removal, we recommend that the 19-inch 

housing is supported in a cabinet or rack with slide rails! 

Short gas paths 

Install the gas analyzer as close as possible to the sampling location. 

Install the gas conditioning and calibration modules as close as possible 

to the gas analyzer. 

Adequate air circulation 

Provide for adequate natural air circulation around the gas analyzer. 

Avoid heat build-up. 

Mount (see page 66) several 19-inch housings with a minimum spacing of
