Direction 5743854-1EN, Revision 1
Section 3.0 Routing Cables
3.1
General
These wires must be kept separated from each other:
• High voltage and power cables must be separated from other cables
• Separate conduits must be used for power and signal wires
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.
3.1.1
Electrical Ducts (Recommended)
It is 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.
3.1.2
Conduit
If conduit is used make sure the conduit is large enough to pull the cable and connector through
with all the other cables all ready in the conduit.
The use of conduit is recommended for cables running overhead between rooms, especially when
a diagonal run provides the shortest cable path.
3.2
Power Distribution
The system power distribution consists of two major components that must either be customer
supplied or GE Healthcare supplied. These are:
• Feeder power from Hospital distribution center to the System Cabinet load power unit (SKL).
• Feeder power must be provided via a WYE transformer only with dedicated ground. Neutral is
not used.
• Power distribution from the System Cabinet load power unit (SKL) to all the components in the
system room.
Usually the feeder power from the Hospital distribution center is customer supplied and the power
distribution within the system is supplied by GE Healthcare.
