3. Setup and Installation
3.1 Components for Installation
Figure 2: Installation Components. This image displays the essential components provided for installation: a 6-foot power cable with a standard US plug, a robust hanging hook, and a safety cable for secure mounting.
3.2 Hanging Installation (Plug and Play)
The light is designed for quick and easy suspended ceiling installation.
- Prepare the Mounting Point: Identify a sturdy ceiling beam or structure capable of supporting the light's weight.
- Attach the Hook: Securely attach the provided US hook to the designated mounting point.
- Hang the Light: Carefully hang the UFO LED High Bay Light onto the attached hook.
- Install Safety Rope: Attach one end of the safety rope to the light fixture and the other end to a separate, secure point on the ceiling structure. This provides an additional layer of security.
- Connect Power: Plug the 6-foot power cord into a compatible AC100-277V power outlet.
3.3 Hardwired Installation
For permanent installations or when a dimmer switch is used, the light can be hardwired. This requires cutting off the pre-attached plug and connecting the wires directly to your electrical system. This procedure should only be performed by a qualified electrician.
- Identify Wires: The power cord contains live, neutral, and ground wires. For 0-10V dimming, there are additional purple (+) and gray (-) wires.
- Connect Wires: Connect the light's wires to the corresponding wires from your power supply and dimmer switch (if applicable) according to local electrical codes. Ensure all connections are secure and insulated.
- Grounding: Always ensure the fixture is properly grounded.
