4.5.1.3 Electrode connections
W A R N I N G
To conform with security standards and to respect the EMC compliancy of the analyzer, this
procedure must be followed when connecting selective, reference, combined and temperature
electrodes to the electronic unit of the analyzer.
Before being connected to the terminal block of the measurement board, electrode cables
must pass through ferrite blocks to minimize the risk of outside interferences that could
cause erroneous measurement data.
For the selective or combined electrode, install the cable gland and pass the cable of into
the electronic unit in the same way as for all other cables (as described in Connecting
peripherals on page 14). Once both wires (measurement and shield) are in place, pass
them both through the ferrite block. Make a loop by passing them through a second time
before connecting them to their respective inputs as illustrated in Figure 5.
Figure 5 Selective or combined electrode connection
For the reference electrode (not applicable in the case of a combined electrode) and the
temperature sensor, install the cable glands and pass the cables into the electronic unit in
the same way as for all other cables (as described in Connecting peripherals
on page 14). Once the reference electrode wire and the two temperature sensor wires are
in place, pass them all through the second ferrite block. Make a loop by passing them
through a second time before connecting them to their respective inputs as illustrated in
Figure 6 (the temperature sensor has no polarity).
