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.

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.
