3.2 Cable Channeling
3.2.1 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
3.2.2 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
3.2.3 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 and Mac-lab cables exit behind the table in the patient room.
For Fast Link cable (C1 cabinet - AW station), the static operation bending radius
must be at least 4 times the outer cable diameter.
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)
NOTE: Specific Recommendations for installation with GE ECG Device such as MacLab,
CardioLab or ComboLab:
•
TRAM RAC in Exam Room with cable 2016134-106 routed back to Control Room
where the other modules & PC are installed.
•
If no GE Maclab cable 2016134-106 installed between the TRAM (Exam Room)
and the Control Room, need to route it so that installation/connection of Physio
module can be made in Control Room.
