4.1.3 INSTALLATION IN THE MRI ROOM 1. Mount electrical box securely to a structural member outside of the safe perimeter (100 Gauss line/10mT) of MRI machinery with a fastener 1/2" diameter x 2" L. (Four holes are provided on the base plate of transformer box). 2. It is recommended not to mount the electrical box on wall. 3. Velcro is provided on the base plate of the electrical box and a rope and snap-on hook is provided on the electrical box to assist in proper installation. 4.
4.2 CELESTIAL STAR CEILING CS2050C-MRI 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.
CAUTION! IF CONSTRUCTING ADDITIONAL SUPPORT STRUCTURES TO INSTALL THE LIGHT, THE LIMITATIONS AND REQUIREMENTS OF THE MRI ENVIRONMENT MUST BE CONSIDERED. NON-MAGNETIC MATERIALS SHOULD BE USED. CONSULT WITH YOUR MRI FACILITY MANAGER IF UNCERTAIN. 4.2.1 INSTALLATION OF THE EXTENSION ARM TO THE CEILING For illustrations please refer to Figure 4 and 5. Attach the extension arm to the ceiling prior to connecting the balance arm to the extension arm.
4.2.2 MOUNTING WITH AN ANGLE L-BRACKET AS SUPPORT CAUTION: WHEN MOUNTING CELESTIAL STAR CEILING MRI LIGHT, CARE MUST BE TAKEN TO USE ONLY NON-MAGNETIC MOUNTING STRUCTURE AND HARDWARE. An angle L-bracket can be used to secure the mounting bracket to a vertical plane above the drop (false) ceiling. Please refer to the dimensions below to determine the appropriate distance to the drop ceiling based on the desired clearance under the lowest point of the extension arm.
A: Floor to Drop Ceiling Distance 7’6” (2,25m) 8’ ( 2,4m) B: Clearance between BOTTOM of transformer bracket to drop ceiling C: Distance you get from bottom of extension arm to floor (Recommended: 6’3” – The user can specify need) 6.5” (165mm) 6.5” (165mm) 5’9” (1,75m) 6’3” (1,9m) 8’6” (2,55m) 6.5” (165mm) 6’9” (2,05m) 9’ (2,7m) 6.5” (165mm) 7’3” (2,2m) Table 1.

Recommendations for mounting Celestial Star MRI ceiling (for hard ceiling to drop ceiling distance greater than 5 feet) When using a set up shown in figure 6: If the drop ceiling to hard ceiling distance is 3 feet or less than 3 feet, then one horizontal plate is recommended. If this distance is more than 5 feet then use of another horizontal plate above the first horizontal plate is recommended for assuring stability of the structure and stability of the light.

These are recommendations only; Sunnex is not responsible for all the material required for mounting.
4.2.3 ATTACH BALANCE ARM TO EXTENSION ARM Follow these instructions to attach balance arm to the extension arm 1. Do not attach the counter weight to the balance arm prior to connecting the balance arm to the extension arm. 2. Connect the male Molex connector with the female Molex connector and ensure that the positive latch on the connectors is achieved. Refer to Figure 3. Position the connection in such a way that the wires will not be compromised by securing the extension arm to the balance arm. 4.
Voltage output: Current: 14V DC 7.5 Amp. DC in secondary Sunnex does not recommend any specific filter but the specifications of the Celestial Star product must be carefully considered when selecting a filter. Some manufacturers that make RF filters are: Amphenol Canada, Spectrum Control, ERNI, Conec. (Amphenol Canada part# FCC17-A3W3AD-2X0 or equivalent filter should be used.) The voltage drop over the filter must be minimal to ensure proper performance of the light fixture.

The light is supplied with a hard service cord (STOW 18/3, 600V, -35 OC to 105OC, 10 Amp per conductor @ 25 OC, approved as water resistant, oil resistant, outdoor use) suitable for ceiling hardwiring applications. This cord has 3 conductors (Hot, neutral and ground). The earth and neutral conductors are labeled as follows: EARTH NEUTRAL N This STOW cord runs through a hole in the transformer box. The outer diameter of the STOW cord is 0.378” (9.66mm). The hole in transformer box is 0.90” (22.
4.3 CELESTIAL STAR DUAL CEILING CS2050D-MRI Before you get started! *Drawing of dual mounting bracket provided in the Appendix *The dual mounted Celestial Star comprises two identical single ceiling mounted lights. The two lights are to be mounted back to back by creating structures described in the single arm installation procedures above.
5. OPERATING INSTRUCTIONS Power-on your light via the rocker switch in the back cover of the lamp head. The Celestial Star MRI is powered by a 200W isolation, step-down transformer that contains an internal thermal cut-off for your added safety. 6. ABOUT YOUR CELESTIAL STAR 6.
MOVING THE CELESTIAL STAR MOBILE When moving the light, please fold the balance arm toward the center of the light to prevent tipping.
6.2 CELESTIAL STAR MRI CEILING CS2050-C-MRI Figure 12: Celestial Star Ceiling dimensions REACH: With the lamp head/balance arm fully extended in the horizontal plane, the reach from the center of the ceiling “S” extension arm to beam center is, 58” (1.5m). If the light is mounted above the center of a 6’6" (2m) exam/treatment table, the beam center will reach 19” (0.5m) beyond its head and foot ends. A 10’ (3m) circle of coverage is available. Refer to figure 12.
CAUTION! DO NOT FORCE MOVEMENT PAST EITHER STOP POSITION, AS THIS WILL CAUSE DAMAGE TO THE ARM END JOINT. LAMP HEAD/YOKE MOVEMENT: The lamp head rotates over 350 degrees at its connection to the yoke. Movement is controlled by grasping either of the in-frame handles, or, with the aid of an added accessory, a sterilizable handle and mount assembly which may be fixed to the center of the lamp head. CAUTION ! DO NOT FORCE MOVEMENT PAST ITS STOP POSITION.
7. SERVICE AND MAINTENANCE ALWAYS bring the light outside the MRI room when performing any service on the light. This includes any cleaning and/or bulb replacements. The ceiling light balance arm can be detached and brought out of the MRI room for maintenance or repair. Assemble the mobile light outside of the MRI room. The safety guidelines of your MRI facility must NEVER be compromised. If in doubt, consult with your facilities manager on proper procedures.
7.2 HANDLE STERILIZATION The Delrin handles may be sterilized as you would any of your stainless steel instruments. However, it is of sufficient diameter to engage a disposable sleeve. The Delrin handle is an accessory for use with the Celestial Star (CS2050C/M-MRI) Specialty light. It is recommended that it is treated as a stainless steel item when submitting it to sterilization process. Two options are recommended: 1. A flash cycle at 275 – 279O F (135 – 137O C), for 16 minutes 2.
