17 Cable Channeling
17.1 General
High voltage and power cables must be separated from other cables. Use a separate trough in
the duct system, or use a separate conduit. Minimize cable length between the line disconnect
and the System Cabinet power unit to reduce voltage regulation problems and wiring costs.
For information about the cables supplied with your system, please refer to Physical Runs .
Raceways or cables trays containing electric conductors shall not contain any pipe, tube or equal
for steam, water, air, gas, drainage or any service other than electrical
17.2 Conduit
Separate conduits must be used for power and signal wires. These wires must be kept separated
from each other.
Using conduit imposes some important considerations when used with this system. Of primary
concern, the majority of cables used are pre–terminated. Pre–termination greatly simplifies
interconnection but makes cable–pulling difficult because of the added dimensions of the
connectors.
Conduit must be large enough to pass the cable and connector through with all other cables already
in the conduit. Also, the size of conduit chosen must allow for future growth. There is the possibility
of additional cables being added later as the system is developed and options are added.
The use of conduit is recommended for cables running overhead between rooms, especially when
a diagonal run provides the shortest cable path
17.3 Electrical Ducts
It’s important that electrical ducts have separate compartments for power and signal wires. These
wires must be kept separated from each other for proper system operation.
Electrical ducts have advantages, when used with a single room or two adjacent rooms. Electrical
ducts combine cabling in a neat and functional appearance, with accessibility and room for
expansion.
NOTE: Medrad AVANTA, IVUS and Mac-lab cables exit behind the table in the patient room.
It is the responsibility of the site planner to provide the appropriate solution to the table
exit (e.g gas box, Clab II, Tram module, connection interface box)
