Before you get started!
Refer to Figure 4 for dimensions
Dimensions and hole pattern of transformer bracket in the Appendix
*It is recommended to install the transformer box outside the MRI room and run the power through an RF
filter (Option 1). In the event the transformer box must the installed inside the MRI room (Option 2), the box
must be secured to a structural member at a safe distance (100 Gauss line/10mT) away from the MRI
machinery. Refer to section ELECTRICAL CONNECTIONS below for guidance.
* The suggested floor-to-(fixed) ceiling height is 9’ (2.7m). While an 8’ (2.4m) minimum is acceptable, it will
affect head clearance for tall people. For ceiling heights over 9’ please see below for instructions. Please
refer to Figure 4 for mounting height guidelines.
* The total weight of the light is 56 pounds (25 Kg). NEVER attempt to affix a ceiling light to a drop (false)
ceiling.
* The light bracket should be mounted against a permanent member just above the drop (false) ceiling. If the
ceiling surface is to be finished, the light is mounted first. A small panel should then be constructed in the
finished ceiling surface, to provide access to the electrical connections and the bracket.

CAUTION: Installations in which there is a great distance between the hard ceiling surface and the drop
ceiling surface, require construction of an additional support structure. This structure must be of adequate
strength and stability, to support the light and prevent any swaying or torque when the light is moved during
use. In some installations, a structure in the form of a rectangle box with an angle iron fixture at its base, is
constructed. At its top, it is bolted to the hard surface above the drop ceiling. At its base, is the angle iron.
The CELESTIAL STAR light bracket is then mounted to the vertical portion of the angle iron, using four (4)
3/8” x 2 1/4” (M10 x 60mm) bolts and 3/8” x 1/2” (M10 x 12mm).
• If metal brackets are in use, the same consideration given to the mounting of a sink, toilet or similar
wall mounted items should be given for mounting of the light.
