ALLOWED CABLES
The 2VOICE bus is NON polarized. The cable (Ref.1083/90 or Ref.1083/92) has been designed to ensure
the maximum distance and dimensions of the system. Because this cable is twisted, a good noise immunity
is ensured.
§
For system max. extensions and types when different kinds of cables are used, see the next
paragraphs.
WARNING ! If multi-pole cables are used, it is absolutely forbidden to short-circuit several conductors
in order to increase the cable section.
§
For long distance branches, it is suggested to reduce to the minimum joint points between cables. For
joints, use devices ensuring a good and lasting connection between cables, protecting the joint against
humidity and bad weather.
