3.0 INSTALLATION
ATTENTION : For location of back boxes, please refer to architectural drawings.
All electrical wiring should conform to the NEC 2002 Code. Some facilities
require hospital grade MC cable. Low voltage wire for Fixation Lights should be
plenum rated cable. Heights should conform to the latest ADA regulations.
3.1 Determine the location for the Power Box “A”. Box “A” should be located in an
accessible area, typically in the open space created by the leg space under a writing
surface or behind a cabinet if a built in Ophthalmic Control System is purchased. This
requires a four-gang box and will contain the high voltage wires. The switched leg from a
switch at the door brings power to Power Box “A” and then is distributed to the various 115
VAC devices. This switch must be a double pole switch that disconnects both the hot and
neutral voltage lines. The fused circuit must be on the hot voltage line. Please see
electrical schematics for exact details. Determine the location for Box “B”. Box “B” the
connections for low voltage functions. Place this single gang box next to Power Box
“A”, approximately 3” apart.
3.2 Determine the location for the Indirect Ophthalmoscope Hanger. Recommend
location: 60” above floor, 36” from sidewall. It requires a single gang box and a 4
conductor low energy wire provided by Varitronics. This wire runs back to Box “B”.
Follow the color code when installing the Hanger to the box. Voltage load: 6VAC, 1 amp
maximum.
3.3 Determine the location for the Fixation and Muscle Lights. These lights require a
single gang box (2) and the 2 conductor (plenum 18 AWG) low energy wire running back
to Box “B”. Fixation light is normally mounted in the patient’s line of sight, 3” from the
ceiling on the wall-facing patient. Muscle light is mounted eye level with patient,
normally 47” from the floor below fixation light. Voltage requirements: 12VDC, 40ma
maximum.
3.4 Determine the location for the Auxiliary Outlet. The Auxiliary Outlet is a 115VAC
switched receptacle that receives its power through the Ophthalmic Control System. This
outlet requires a single gang box and is connected to the Power Box “A”, wire 5. This is also
available on faceplate of single Box “A”. Maximum load: 60 watts.
