All low voltage connections are itemised on the white label below the connector terminals,
see Figure 6 for details.
Figure 6
The cables from the katharometer/reactor unit are identified by number tags that correspond
to the terminal numbers on the label. The two heavier wires (labelled 9 and 10) in the black
cable from the katharometer should be connected to the DIN-rail mounted terminals between
the two carriers.
NOTE
The cables supplied with the katherometer and reactor assembly must not be extended
because they form part of the product certification.
AC supply wiring should be connected to the L, N and E terminals underneath the “Live
Terminals” warning label.
WARNING
Take care to ensure that AC power is not present on the wiring before
removing the protective cover. Ensure also that the protective cover is
replaced before AC power is re-applied to the wiring.
IMPORTANT POINTS TO NOTE
• It may be necessary later to remove the katharometer if it should become
contaminated. Its connecting cable should therefore be routed to assist in its removal.
• Allow sufficient space around the katharometer/reactor assembly for withdrawal of the
quartz reactor tube to the right.
• The electronics and any intermediate electrical junction boxes etc. must be mounted in
a well ventilated area so that any fugitive corrosive gases do not contaminate
these items.
• It is essential that the katharometer and its corresponding identity module (KIM),
which is mounted in the control electronics unit,
have the same serial number.
