LIGHTING
NOTE: Construction methods are always improving. Please refer to www.trex.com for the most up-to-date installation requirements.
General Information
» Refer to www.trex.com for instructional videos on
how to install Trex Decklighting.
» USE TREX TRANSFORMER ONLY. Use of any other
transformer voids warranty.
Planning
NOTE: When designing your deck, plan locations of
lights, power supply, timer, and dimmer. These should be
accessible for service. Installing a GFCI outlet is REQUIRED
to help prevent damage to lighting from electrical surges.
1. The dimmer remote will work in a
30' (9 m) radius of the unit.
2. Dimmer should be installed in a
dry location.
3. Timer must be installed
vertically with receptacle
facing downwards. Timer must
be at least 1' (.305 m) from
ground level when installed as
per federal safety code height
regulations. Timer must be in view of the sun to use
the dusk/dawn feature.
Installing Wiring
NOTE: It is recommended to install wiring and splitters
before decking and railing have been installed.
» Use male-to-male connection wire (lengths vary)
that will connect to each required splitter.
1. Wiring must be run under
decking structure and
behind stringers. DO NOT
run wires between deck
boards and joists. Staple to
frame with cable staples at
least 1/4" (6 mm) wide.
DO NOT crush wire
insulation with staple.
2. Wiring can be run under deck and behind risers.
Staple to frame with cable staples at least 1/4"
(6 mm) wide. DO NOT crush wire insulation with
staple.
3. Remove 5' (1.52 m) lead wire that is connected to post
cap and attach wire to post with male connection at
top of post (female connection would be at bottom of
post and connect into splitter). Avoid running wire on
side of post where railing brackets or deck rail lights
will be installed. Leave approximately 6" (152 mm) of
lead at top to make connections. Staple to frame and
posts with cable staples at least 1/4" (6 mm) wide.
DO NOT crush wire insulation with staple.
Making Connections
1. Install splitters to
inside of framing using
hardware provided.
Install at every post
base where lighting is
present and depending
on spacing in between
each riser and recessed
light.
2. Attach male lead from lights to female connections
on splitter. Also attach male-to-male connection
wires in between each splitter. Continue until all
wiring from lights are attached to splitters and
connector wires are attached in between splitters.
3. Cap off all unused female connections on splitters
using caps provided or weather-resistant silicone.
