Control Unit (CU-4E-FM/FMH)

Download the Control Unit (FM/FMH), Installation Guide PDF: English rev.07 | German rev.07 | French rev.07

Overview

The Enlighted Fixture Mount Control Unit interfaces with Enlighted sensors and ballast or LED drivers to control light behavior intelligently. The Control Unit also contains a power metering chip that enables the Enlighted control network to measure power in real-time as well as energy consumption over time.

The Fixture Mount Control Unit (CU-4E-FMH) is designed to be mounted inside fixtures and NEMA-rated enclosures. Sheet metal screws are typically used to mount the Control Unit in these environments. Mount the full-length CU-4E-FMH in place of the CU-3E, or remove the break-off tab to create a smaller form factor for a reduced footprint.

Control Unit

Installation

Supplemental Components:

  • Enlighted Control Unit

Tools you may Need

  • Two mounting screws, as appropriate for mounting the Control Unit to the inside of the luminaire

Caution

A qualified electrician must perform installation and maintenance following local, state, and national electrical codes (NEC) and requirements.

Procedure:

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, shorten the CU mounting tab by snapping off the tab at the notch on the CU's AC input side.

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 you can easily reattach the ballast cover.

Step 11: Install the RJ45 sensor cable between the Control Unit and the Enlighted sensor. Please do not use the 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).

Additional Installation Instructions for Use with a Dimming Ballast

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, you may connect the dimming wires in parallel (violet to violet and grey to grey) for all drivers on that channel.

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 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.

Completing the Installation

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 a full bright state and then may cycle or dim, based on the sensor commissioning status or programming.
