Installation of Transformer:
1. Loosen Set Screw on the Rail Adapter of the Canopy.
2.
Raise the Monorail into the Rail Adapter, then tighten
Set Screw. If needed, the opening of the Rail Adapter
can be increased by loosening the Allen Screws,
then retighten.
3. Turn on power to system.
Operate system for 5 minutes, then verify that
the connections are running cool to the touch.
Installation of Monorail:
Junction
Box
1. Extension Wires are supplied to connect
the Building Wires to the Transformer leads.
Connect white neutral wire to the white wire,
and black hot wire to black wire with wire nuts.
The Ground Wire may be green or bare copper,
connect it to the green wire and mounting
crossbar ground wire using a wire nut.
2. Carefully pass the Extension Wires through
the center hole of the supplied Crossbar/Threaded
Nipple assembly, then secure crossbar to the
Junction Box with Mounting Screws.
3. Raise the Transformer Assembly onto
the Threaded Nipple, then secure with
the Washer, Star Washer and Hex Nut.
4. Connect the Extension Wires to the Transformer
Leads with wirenuts. Connect white neutral wire
to the white wire, and black hot wire to black wire
with wire nuts. Then connect the bare grounding
wire to the green wire.
5. Install the Transformer Canopy by positioning onto
the Transformer Assembly and securing with
the three Canopy Screws.
6. The monorail can now be connected to the canopy.
NOTE:
For applications where the monorail is not directly
below the canopy, utilize the flexible feed provided.

IMPORTANT SAFETY INSTRUCTIONS:
a. Read all instructions.
b. Do not conceal or extend exposed conductors through a building wall.
c. Do not install this system in wet locations.
d. For low voltage exposed insulated conductor systems required by 30.1(c)
do not install any part of this system less than 7 feet (2.2m) above the floor.
e. To reduce the risk of fire and burns, do not install this lighting system where
the exposed bare conductors can be shorted or contact any conductive materials.
f. To reduce the risk of fire and overheating, make sure all connections are tight.
g. Do not install any luminaire closer than 6 inches (15.25 cm) from any curtain,
or similar combustable materials.
h. Turn off electrical power before modifying the lighting system in any way.
i. Do not connect to an ungrounded supply.
SAVE THESE INSTRUCTIONS
The SA150 is a 150 watt electronic
transformer, designed to power
multiple luminaires with a combined
load of 150 watts or less. For example,
if using 50 watt halogen pendants, do
not connect more than three (3) total.
The minimum load required is 50 Watt
For dimming, an electric low voltage
dimmer is recommended.
