5. Setup and Installation

Follow these steps carefully for proper installation. It is recommended to have two people for installation due to the length of the fixture.

5.1. Prepare for Installation

• Turn off power at the circuit breaker before starting.
• Unpack the fixture and components. Inspect for any damage.
• Determine the desired mounting location and height. The adjustable wire slings allow for heights up to 58.26 inches (148 cm).

5.2. Suspended Mount Installation

1. Install Ceiling Anchors: Mark the positions for the ceiling anchors according to the fixture's length. Drill pilot holes and insert the plastic wall anchors. Secure the length adjuster bases to the ceiling using the self-tapping screws.
2. Attach Wire Slings: Connect the wire slings to the length adjuster bases on the ceiling.
3. Connect to Fixture: Carefully attach the other end of the wire slings to the designated attachment points on the top of the linear light fixture. Ensure they are securely fastened.
4. Adjust Height: Use the length adjusters to set the desired hanging height of the fixture. Press the button on the adjuster to release or tighten the wire.

5.3. Electrical Connection

• Locate the quick-connect terminal block on the fixture.
• Connect the main power supply wires (Live, Neutral, Ground) to the corresponding terminals on the block. Ensure correct polarity (Black to Black, White to White, Green/Bare to Green/Ground).
• If using 0-10V dimming, connect the dimmer wires to the appropriate dimming terminals on the fixture.
• Ensure all connections are secure and insulated.

5.4. Seamless Connection (for multiple 4FT fixtures)

For continuous runs of 4FT fixtures, use the quick-link ends:

1. Open End Cap: Remove the end cap from one end of the first fixture and the corresponding end of the next fixture.
2. Quick Connect: Align and push the quick-link ends of the two fixtures together until they click into place, creating a seamless physical and electrical connection.
3. Fasten Joint: Secure the joint using the provided screws or fasteners to ensure stability.

Note: Only 4FT suspended linear lights support single power feed connection for linked units (up to 10 lights). For 8FT lights, you will need to run separate power cables to each fixture.
