LCU NEMA Description
LCU NEMA is a luminaire control unit, easily installed on top of the luminaire utilizing a standard (twist
and lock) NEMA socket. LCU NEMA is a unit of the T-Light Galaxy star network. Control features offer
On/Off and dimming level operations. Monitoring features include identification of lamp and
measurement of electrical parameters. The LCU NEMA is controlled by the Smart Lighting System
Control Management Software (CMS) via a Data Communication Unit (DCU) gateway.

Standard Features
Light sensor - Operates as a photocell with the integrated microcontroller and is used as a backup
light control in the event of microcontroller failure.
Energy meter - Continuous measurement collection and aggregation with 1% accuracy.
Integrated RF antenna.
Over the air firmware updates.
Each unit is configurable as a repeater, resulting in one additional ‘hop’ from the DCU.
Real Time Clock.
Network data is protected by AES 128 encryption and, optionally, AES 256.
Relay Control for LED driver/ballast power.
Alarms for power extremes and maximum temperature.
“Auto Detection and Verification” Software
“Auto Detection and Verification” Software
The LCU NEMA includes the Telematics “Auto Detection and Verification” software that automatically
detects and stores the ballast type (1-10V or DALI) in the LCU. The ballast type is then retrieved during
the commissioning process, thereby eliminating the need to enter it manually into the CMS.
Optional Features
Built-in GPS receiver for full auto-commissioning.
Built-in NFC chip for data exchange with hand-held device.

Regulation Information
FCC Part 15 Regulation Class B device
The digital circuit of this device has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 90 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment
generates uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
-Consult the dealer or an experienced radio/TV technician for help.
Industry Canada Class B Notice
This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the
following two conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause undesired

Warning: To prevent damage due to power network voltage surges, it is
mandatory that you also provide and install a surge protection device to protect
the LCU and the luminaire driver.
Warning: To prevent damage due to power network current surges, it is
mandatory that you also provide and install a 10 amp slow-blow fuse or circuit
breaker to protect the LCU and the luminaire driver.
Installation Requirements
Mandatory Customer-Supplied Equipment
System integrity for the LCU NEMA is ensured with the mandatory installation of customersupplied voltage and current surge protection equipment.
Mandatory Voltage Surge Protection
Mandatory Current Surge Protection
Location
The LCU NEMA is installed on the top surface of the luminaire cover utilizing a standard (twist
and lock) NEMA socket.
Post-Installation Commissioning
In order for the installed LCU NEMA units to be recognized in the Telematics Wireless Smart
Lighting System, the serial numbers and GPS coordinates of the LCU NEMA units must be added
to the CMS Equipment Inventory as part of the commissioning process. The level of automation
in the Commissioning process depends on the optional equipment installed in the LCU NEMA:
GPS – Commissioning is fully automated. Commissioning is complete after the CMS
Administrator executes the relevant command.
NFC – Commissioning is partially automated. The required serial number and GPS coordinates
are obtained at the installation site with an Android smartphone and a Telematics app.
Commissioning is complete after the CMS Administrator executes the relevant command.
No GPS or NFC – Commissioning is a partially manual process:
11
◦ Installer obtains the GPS coordinates of the LCU NEMA with a handheld GPS device.
◦ Installer records the serial number and GPS coordinates.
◦ CMS Administrator imports the recorded values into the CMS Equipment Inventory, one by
one or by batch.
