INSTALLATION INSTRUCTIONS 1
IMPORTANT SAFEGUARDS
When using electrical equipment, basic safety precautions
should always be followed, including the following:
TO PREVENT MRI MACHINE INTERFERENCE, ALL DC POWER AND
DIMMING SIGNAL WIRING MUST BE COMPLETELY SHIELDED
WITHIN GROUNDED ALUMINUM CONDUIT AND A SUITABLE MRI
ROOM EMI FILTER MUST BE INSTALLED ON EACH LINE.
THIS PRODUCT MUST BE INSTALLED IN ACCORDANCE WITH THE
APPLICABLE INSTALLATION CODE BY A PERSON FAMILIAR WITH
THE CONSTRUCTION AND OPERATION OF THE PRODUCT AND
THE HAZARDS INVOLVED. DISCONNECT POWER TO ALL CIRCUITS
BEFORE WIRING FIXTURE. INSTALL IN ACCORDANCE WITH ALL
NATIONAL, STATE, AND LOCAL CODES. DO NOT CONNECT TO
AN UNGROUNDED SUPPLY. WIRING CONNECTIONS MUST BE
MADE INTERNAL TO THE ENCLOSURE. FAILURE TO INSTALL
UNIT ON A MECHANICALLY-SOUND SURFACE MAY RESULT IN
PERSONAL INJURY, PHYSICAL DAMAGE, OR POTENTIAL FIRE
HAZARD. USE INSTALLATION PROCEDURES APPROPRIATE FOR
AN ENVIRONMENT INVOLVING MRI AND SENSITIVE ELECTRONIC
EQUIPMENT. READ ALL FIXTURE MARKINGS AND LABELS TO
ENSURE CORRECT INSTALLATION OF FIXTURE. SUPPLEMENTAL
INSTRUCTIONS MAY BE LOCATED ON THE FIXTURE, IN ADDITION
TO THIS INSTRUCTION SHEET, REGARDING ORIENTATION, OR
MOUNTING RESTRICTIONS. READ INSTRUCTIONS PROVIDED
WITH THE MEDMASTER™ MRIPS-312 EXTERNAL POWER SUPPLY
FOR PROPER INSTALLATION AND ELECTRICAL CONNECTION TO
THE LIGHTING SYSTEM.
SAVE THESE INSTRUCTIONS
CUSTOMER ACKNOWLEDGMENT
CUSTOMER ACKNOWLEDGES THAT THESE INSTALLATION INSTRUCTIONS ARE PART OF THE PRODUCT
SPECIFICATION, AND THAT THE ATTACHED INSTALLATION REGISTRATION FORM WILL BE PROVIDED TO THE
INSTALLER TO SIGN AND RETURN TO KENALL AFTER INSTALLATION IS COMPLETE. THIS SIGNED RELEASE IS

INSTALLATION INSTRUCTIONS 2
This instruction sheet applies for the Kenall
MedMaster™ MRIDL6VL2 DownLight. A separate
instruction sheet is provided in the MRIPS-312 external
power supply. Both sheets are intended to provide
comprehensive instructions on fixture installation and
wiring.
3. Bottom of die-cast frame should be flush with room
side surface of ceiling panel. See Figure 2. Adjust
mounting brackets by loosening four (4) wingnuts
(inside fixture) and adjust fixture to correct height.
Re-tighten nuts after adjusting.
The MedMaster™ MRIDL6VL2 lighting system contains
sensitive electronics. Take care to avoid damage
by improper handling or static electricity discharge
(ESD). Either type of damage could render the system
inoperable or cause latent failure.
Make sure all hardware and equipment required for
installation, but not supplied with the luminaire, is
non-ferrous and suitable for installation within an MRI
room.
I. LUMINAIRE MOUNTING PROCEDURE – DROPIN CEILINGS
1. Cut an 8.125" diameter hole in ceiling panel and
install panel.
2. Insert conduit or c-channel (by others) through
mounting brackets. Bend brackets to secure. Lift
fixture into ceiling through adjacent opening and
position over cutout. See Figure 1 below.
II. LUMINAIRE MOUNTING PROCEDURE –
DRYWALL CEILINGS
4. Insert conduit or c-channel (by others) through
mounting brackets. Bend brackets to secure.
5. Mount fixture in ceiling so that the weight of the
fixture is supported by framing material and/or
hanger wires secured to the building structure.

6.
Bottom of diecast frame should be flush with room
side of ceiling surface (figure 4). Adjust mounting
brackets by loosening (4) wingnuts (inside fixture)
and adjust fixture to correct height. Re-tighten
wingnuts after adjusting.
III. ELECTRICAL CONNECTION
7. Mount and wire the MRIPS-312 external power supply per the procedures provided in the supplementary
instruction sheet. Run conduit and DC wiring to an MRI room EMI filter sized to the load of the power supply
(supplied by others). Make sure wiring is completely enclosed in grounded aluminum conduit. Any gaps,
regardless of size, must be closed or wrapped in copper foil tape.
8. If a 0-10V dimmer is to be connected, install at this time. Dimmer must be installed outside the shielded MRI
environment with an intermediate MRI room EMI filter to the luminaires. Kenall recommends using a Leviton®
lllumaTech™ IP710 series dimmer or Grafik Eye GRX-TVI control interface. Contact Kenall for suitability of using
an alternate sink-type 0-10V dimmer.
9. After the luminaires are mounted and secured, access the external junction box to gain access to supply
connections. Each wire is labeled and color coded for easy identification. The junction box cover is located on
the side of the luminaire housing.

wires. Make sure wiring is completely enclosed in grounded aluminum conduit. Any gaps, regardless of size,
must be closed or wrapped in copper foil tape. Special attention should be paid to the wiring entry point into
the shielded space. See Figure 5.
12. Make DC supply and (optional) dimmer control connections within each luminaire. Cap gray and violet leads if
dimmer is not connected.
13. Using at least an 18 AWG wire, ground the last housing in the sequence to the shielded ceiling. This can be
done by fastening the wire to one of the luminaire’s junction box screws.
14. Reinstall all provided bracketry and internal enclosures provided with the luminaire. These parts are critical to
the overall EMI shielding of the system.
15. Connect power to external power supply and test for proper operation of lighting system. Make sure all LEDs
are lit and dimming operation works as intended (if connected).
16. Test operation of lighting during MRI machine idle mode and during scanning operations.
17. Fill out the Installation Registration Form (attached to MRIPS-312 instruction sheet) and fax to Kenall at
(847) 360-1781.
