EL3000 CONTINUOUS GAS ANALYZERS
 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 mm 2 (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 mm
be more than 0.5 mm
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 cross-section
0.25 mm 2 (e.g. Thomas & Betts, Type LiYCY).
 Max. length of the RS232 leads 15 m.
 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.
