Installation Steps
Step 1
: Switch off the circuit breaker supplying power to
the light fixture.
Step 2
: Open the fixture cover and remove the cover for
the ballast cavity. The ballast and its wiring should now be
visible.
Step 3
: Utilizing a voltmeter, verify that power is off to the
ballast. If power is present, stop work, identify, and switch
off the circuit breaker.
Step 4
: Place the Control Unit (CU) in the desired location
and secure it with mounting screws. If desired, the CU
mounting tab can be shortened by snapping off the tab
at the notch on the AC input side of the CU.
Step 5
: Disconnect the “Hot” wire (Line) of the ballast
from the power input wire.
Step 6
: Connect the power input “Hot” wire (Line) to the
Control Unit black Wago
Lin
(Line In) connector.
Step 7
: Connect the ballast power input “Hot” wire to the
Control Unit red Wago
Lout
(Line Out) connector.
Step 8
: Connect the power input (Neutral) wire to either one
of the two white Wago
N
(Neutral) connectors on the CU.
Step 9
: Connect the ballast (Neutral) wire to either one of
the two white Wago
N
(Neutral) connectors on the CU.
Step 10
: Bend wires into place such that the ballast cover
can easily be reattached.
Step 11
: Install the RJ45 sensor cable between the Control Unit
and the Enlighted sensor. Do not use RJ12 cable as it may
damage the sensor port. Refer to the corresponding
Sensor
Installation Guide
for connecting the cable between the
sensor and the Control Unit (CU).
Completing the Installation
Step 2
: Connect the gray wire (-) from the dimming ballast to
channel A gray Wago terminal on the Control Unit. Repeat for
channel B if required.
Step 1
: Connect the violet wire (+) from the dimming ballast to
channel A violet Wago terminal on the Control Unit. Repeat for
channel B if required.
Step 1
: If the sensor is mounted outside of the luminaire, use
a snap bushing in the knockout hole on the lighting fixture to
route and protect the sensor cable. If the sensor is mounted
within the luminaire, then bushing is not needed.
Step 2
: Install the cover for the ballast cavity and apply
power to the newly wired lighting fixture.
Step 3
: The lights should turn on to full bright state, and then
may cycle or dim based on the sensor commissioning status
or programming.
The Control Unit (CU-4E) can connect to two dimming
ballasts on two separate channels (channels A and B) for
“Tunable White” applications. If using both dimming
channels, gently break the tab above channel B. For single
channel dimming, use channel A terminals only. For multiple
dimming drivers on the same channel the dimming wires may
be connected in parallel (violet to violet and grey to grey) for
all drivers on that channel.
Installation and maintenance must be performed by a
qualified electrician in accordance with state, local, and
National Electrical Codes (NEC) and requirements.
The Fixture Mount Control Unit must be installed in a UL-
rated fixture or enclosure rated for this application.
