Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors, Gasket
- Unpack and Inspect the Unit
Carefully unpack the FB24ST Fireball Light and inspect it for any damage that may have occurred during transit. If damaged, do not proceed with installation and file a claim with the carrier.
- Mount the Light
Using the gasket as a template, mark and drill three 3/16” (4.8 mm) holes for mounting screws and a 1” (25.4 mm) hole for wiring. Secure the light to the mounting surface using the provided screws.
- Make Electrical Connections
Ensure power is off. For AC models, connect the two black leads to the phase side of the incoming and outgoing power, the two white leads to the common side, and the green/yellow lead to earth ground. For DC models, connect one red lead to the positive side and the other red lead to the outgoing positive, one black lead to the negative side and the other black lead to the outgoing negative, and the green/yellow lead to earth ground.
- Verify Connections and Power On
Double-check all connections for correctness and ensure all screws are tightened. Turn on the power to the system and test the light to ensure it operates correctly.
