4 Safety recommendations and warnings
Warning! Carefully read the warnings below before using or working with the product!
• Always adhere to local rules and regulations when installing or using the LED fixture.
• Do not open or disassemble the LED fixture; there are no serviceable parts inside. Opening or modifying the LED fixture
can be dangerous and will void the warranty.
• This product may cause interference to radio equipment and should not be installed near maritime safety communications
equipment or other critical navigation or communication equipment operating between 0.45-30 MHz.
• Do not use the LED fixture when either the LED fixture or its power cord are damaged. Replace the power cord only
with original, certified cords.
• Modifications to the cords can lead to unwanted electromagnetic effects, which makes the product not comply with
legal requirements.
• Do not expose the LED fixture to:
- (ambient) temperatures outside the specified range;
- dust and contamination;
- direct sunlight during use or HID light that could heat up the fixture.
• Always disconnect the LED fixture from mains before performing any maintenance.
• Always allow for a cool-down period of at least 30 minutes before touching the LED. Touching the LED when the fixture is
lit or immediately afterward can result in severe burns!
• Do not use the LED fixture near flammable, explosive or reactive substances. Do not use sulfur vaporizers.
• The installation and use of the LED fixture is the responsibility of the end user. Incorrect use or installation can lead
to failure and damage to the LED fixture. Damage to the LED fixture and electronic circuitry as a result of incorrect
installation and use voids the warranty.
• The minimum distance between adjacent lighting equipment is 4 inches (10.16 cm). The minimum distance between lighting
equipment and combustible materials is 4 inches (10.16 cm).

7 Installation
Warning! Mounting and installation of the LED fixture may only be executed by certified service personnel, in
accordance with applicable local laws and regulations.
Warning! The installer is responsible for correct and safe installation.
Warning! Ensure the local cabling can support the voltage and current requirements of the LED fixture.
Warning! Avoid coiled cords and keep mains leads separated. This prevents electromagnetic interference.
Warning! Do not connect or disconnect the LED fixture under load.
7.1 Installing the LED fixture
Warning! When mounting, attach the fixture to something that can support its entire weight.
• Switch off main power.
• Secure the hanging brackets to the fixture (fig. 3).
• Hook the unistrut hanger onto the LED fixture hanging brackets (fig. 4).
• Holding the LED fixture by the unistrut hanger with 2 hands, lift the fixture and place the hanger onto the unistrut as
shown in the picture (fig. 5).
• The center of the fixture is located 4-3/16" from the front of the unistrut hanging bracket (fig. 6).
• Install safety wire (B) as shown in picture (fig. 7).
• If a controller is not being used, make sure the dummy plug is inserted into the “IN” RJ45 communication port (fig. 8).
• Plug the female main power into the LED fixture's male power input (fig. 9). Align the white arrow on the end of the
power connector with the "Closed Lock" symbol on the fixture. Press in until there is a “click” sound.
Make sure power cords:
1. Are not concealed or extended through a wall, floor, ceiling, or other parts of the building structures.
2. Are not located above a suspended ceiling or dropped ceiling.
3. Are not permanently affixed to the building structure.
4. Are routed so they are not subject to strain and are protected from physical damage.
5. Are visible over their entire length.
6. Are used within their rated ampacity as determined for the maximum temperature of the installed environment
specified in the instructions.

7.2 Preparation for use with a controller
Using a daisy-chain setup, a maximum of 100 LED fixtures can be connected to each controller
channel. Up to 500 LED fixtures can be connected with the use of splitters. Refer to Section 7.4.
Using the Fixture:
1. Without a Controller
a. The included dummy plug on the input of the first fixture will ensure continuous operation at 100% output. The plug has
a circuit board embedded which simulates 100% output (fig.10).
Warning! Please do not confuse this with a normal RJ45 terminal.
Warning! Only to be used on the “IN” port of the fixtures. Please do not insert this in any OUT port of a fixture (fig.11).
b. To turn fixtures off, you must rely on line voltage control at this point.
c. You have the option of daisy chaining explained in Section 7.4 or using a dummy plug in each individual fixture.
