Installation and maintenance Manual

Four wires per Extension are connected at the Main Equipment. Spare wires must be neatly laid back

away from the connectors. To prevent cross talk or interference, cable pairs should not be split or the

spare wire of cable pairs used.

All Extensions should connect into standard line jack units. Extension cabling

should not be exposed to high voltage surges, (for example, surges induced by

lightning or neighbouring high current-carrying cables). If this is a possibility

external protection of the Main Equipment and Extensions using ‘earthed line

surge protectors’ is essential.
