Mounting Height of the Interface Plate
The installed height of the interface plate (black) is the determining factor for ensuring a clearance
height of 2000 mm for the spring arm.

The clearance height is below 1.9
m. Therefore, the vertical tube
must be cut to 300 mm.

Cut the tubes and threaded bolts
of the ceiling frame to match this
measurement. Cut the threaded
bolts 100 mm longer than the
tubes.

> 4.25 m 3.315 m ± 10 mm 800 mm
An additional custom made con-
struction is necessary to fulfill the
required interface plate height or
clearance height > 2.1 m. Consult
with Brainlab on possible solu-
tions.
Recommended Position of the Ceiling Mounted Monitor
• Brainlab recommends positioning the ceiling-mounted monitor at a longitudinal distance of
1800
+500
mm and a lateral distance of 1250
+500
mm from the isocenter. The position depends
on other existing ceiling-mounted objects.
• Brainlab recommends positioning the ceiling-mounted monitor on the side of the couch that is
opposite to the bunker entry.
• Risk of collision with gantry is still possible but not critical, as the spring arm will give way.
Nevertheless, the longitudinal distance should not drop below 1.5 m.
• The monitor will reach the primary beam area. Therefore, instruct your staff to park the monitor
in a safe position.
• Adjust the maximum distance between the black interface plate (at height of suspended ceiling)
and the ceiling-mounted distribution box to the available cable length of 4 m between the two
devices.
• The horizontal arm must not collide with the camera. To avoid collision, do not simultaneously
install the arm at the same height as the camera and closer than 1250 mm to the isocenter.
