Refer to Figure 1.
You are responsible for permissibility of the installation at site with respect to applicable
local or regional standards. This might affect the choice of cable routes, specifications of
mains power and data cables, connection to protective earth and the choice of installation
locations of system components. Fire protection engineering aspects (plenum rating) may
be affected when installing cables and system components.
NOTE: Pull the cable length with sufficient slack to reach the final components. Provide 300 mm
slack within both power distribution boxes.
NOTE: If the generator(s) are located in a room other than the treatment room, both rooms must
be brought to the same potential.
NOTE: If the Computer Cabinet is not located in the treatment room and its housing shall be
grounded locally, the potential difference between the local PE and treatment room PE must not
exceed 24V AC or 60V DC (see comment 1 in Figure 36).
NOTE: Correct PE grounding of the linac and couch is presumed. PE grounding is usually defined
with the linac electrical cabling diagrams or was defined by a hospital electrician.
