SAFETY PRECAUTIONS
To limit the risk of personal injury, always follow these precautions before connecting
analogue and digital exchange line circuits and ODX circuits :
•
Never install telephone wiring during a lightning storm.
•
Never install telephone jacks in a wet location unless the jack is specifically designed
for wet locations.
•
Never touch uninsulated telephone wires or terminals unless the line has been
disconnected at the network interface.
•
Use caution when installing or modifying telephone lines.
SYSTEM CABLING
All connections to the DCS 70 system are made by way of a system distribution frame (SDF)
except for the 240VAC power and back-up battery. All cabling to and from the SDF should
be made using ACA approved 0.4mm or 0.5mm twisted pair cable.
Refer to Chapter 9 of DCS I&M manual for details of maximum cable lengths
The KSU is connected to the SDF using cable assemblies terminated with an AMP-Champ
type connector on one end and a 10 Pair Krone connector on the other. The AMP-Champ
connectors insert into sockets on the KSU motherboard and Expansion Cabinet and the
Krone connector forms the system SDF. The cable assemblies can be customer supplied or
are available as items supplied with the systems. Refer to tables below. The retaining screw
on the Champ connector should be secured to hold the connector in place on the KSU and
Expansion Cabinet boards.
