IMPORTANT SAFEGUARDS:
When using electrical equipment, always adhere to basic safety precautions including the following:
IMPORTANT SAFETY/ OPERATING INSTRUCTIONS
1. Read all instructions.
2. Do not conceal or extend bus bar con-
ductors (Flex 12 Trac) through a building
wall.
3. Do not install this system in damp or wet
locations.
4. To reduce the risk of fire and burns, do
not install this lighting system where the
uninsulated open bus bar conductors
can be shorted or contact any conductive materials.
5. Do not install any luminaire closer than
6 inches (15.25 cm) from any curtain, or
similar combustible material.
6. To reduce the risk of fire and overheating, make sure all connections are tight.
7. Turn off electrical power before installing
or modifying the system in any way.
8. Use 10 or 12 gauge wire to connect the
output to the Trac.
9. These transformers are intended for use
with Juno Flex 12 Series or Trac 12/25
Series low voltage lighting systems only.
PARTS LIST
Open the carton and identify all of the following parts:
(1) Chassis / transformer assembly (A)
(1) Cover (C)
(1) Knob (K)
(1) Parts bag including:
(1) Mounting strap (B)
(1) Grommet (G)
(2) Nuts, 1/8 inch (N)
(1) Nipple, 1/8 x 2 3/4 inch (Q)
(1) Ground screw (S)
(2) Wire nuts
PRODUCT FEATURES
Juno’s surface mounted power units are
used to convert 120 volts AC to 12 volts
nominal to provide power to the Flex 12
trac. The Trac length should not exceed 24
feet in either direction from the feed. The
power units are designed to be mounted
to a standard ceiling mounted junction box
that is adequately supported. They can
be used with one or two Pendants, or with
the Flexible Feed (Pendants and Flexible
Feed sold separately). The power units are
capable of supporting up to 20 lbs. They
should not be mounted in any location that
may entrap heat.
The TF6150E is capable of operating from
50 to 150 watts of lamp load and is dimmable with most higher quality incandescent
dimmers. In some cases, dimmers designed
for electronic transformers may be necessary for optimal dimming results. The unit
has short circuit and overload protection that
will automatically reset itself when the short
or overload is removed.
The TF6300 is capable of operating from
150 to 300 watts of lamp load and is dimmable only with dimmers specifically
designed for magnetic transformers. To
protect against an overload or short circuit,
the unit contains a circuit breaker that must
be manually reset after the short or overload
has been removed.
INSTALLATION
WARNING: Make sure power is off
before assembly
1. Make sure that the supply wires protrude
from the junction box at least 7 inches.
2. Thread the nipple (Q) through the nut
(N) and strap (B) with the tapered side
away from the nut as shown. Attach the
ground screw (S) to the strap.
3. Pass the supply wires from the junction
box through the nipple as shown. Secure
the strap to the junction box with two
screws. Connect the ground wire from
the junction box to the ground screw on
the strap.
4. Adjust the nipple to protrude 2 inches
from the mounting surface and lock in
place with the nut.
5. (TF6300 only) Loosen the two wing nuts
(W) on the center mounting bracket (M)
of the transformer assembly and rotate
the bracket out of the way.
6. Pass the supply wires and the nipple
through the center of the assembly (A).
Raise the assembly to the mounting
surface. Place the remaining nut over
the supply wires and thread it onto the
nipple to hold the assembly in place.
7. Rotate the assembly if necessary to orient the pendant(s) as desired, and finish
tightening the nut to secure the assembly in place.
8. Connect the white and black supply
wires to the stranded input wires from
the assembly with the wire nuts provided.
9. (TF6300 only) Carefully bend the supply
wires to the side, rotate the top bracket
back in place, and tighten the wing nuts.
10. Install the Pendant Feed or Flexible
Feed per the appropriate instructions on
the following page.
----- See steps 11-15 on back. -----
16. Connect the feed wires to the terminal
block (TB). CAUTION: For all connections, make sure that the stripped wire
is fully inserted into the connector, all
strands of copper are inserted in the terminal and all 4 screws are tight.
17. Connect the green ground wire from the
assembly to the tab (T) on the inside of
the cover (C).
18. (TF6300 only) Make sure that the circuit
breaker switch (CB) located on the side
of the assembly, is on.
19. Put the cover in place and secure it to
the assembly with the knob (K). Install
the Trac and fixtures per the instructions
included with them.
20. Apply AC power. Confirm that all fixtures
function acceptably. Adjust fixtures as
desired.

SAVE THESE INSTRUCTIONS
Flexible Feed, Using:
TF950 Flexible Feed Kit &
TF21 Electrical Feed Cylinder
Note: The Flexible Feed is not intended to
support the Trac or any weight, only to provide power to the Trac.
11. Insert tinned end of wires through holes
in top of feed cylinder and firmly tighten
terminal screws.
12. Pass wires through top cap and screw
cap onto feed cylinder.
13. Pass wires through grommet (G) in
cover. Determine cord length, leaving
some slack and tighten clamp in place.
14. Hook wire onto bracket.
15. Return to step 16 on the previous page.
Pendant Feed, Using:
TF900 Series Pendant Stem, &
TF21 Electrical Feed Cylinder
11. Thread two nuts on top of stem leaving
space between nuts. Slide top cap onto
stem. Install and tighten bushing onto
stem.
12. Cut two pieces of 10-ga. solid copper
wire to length. Strip one end of each
wire 5/8”. Tightly bind one wire under
each feed cylinder terminal screw.
13. Push wire through stem and screw top
cap onto Feed Cylinder as shown. Pass
assembly through cover.
14. Carefully bend wires at top of stem
90˚ and push assembly onto bracket.
