How to Install the FB24ST Fireball Light
This guide provides step-by-step instructions for installing and wiring the FB24ST Fireball Light for optimal performance.
Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors
- 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 attempt to install and file a claim with the carrier.
- Mount the Light
Choose a suitable mounting location and secure the light to a flat surface or a 1/2-inch NPT or M20 threaded pipe. For surface mounting, use the gasket as a template to mark and drill three mounting holes and a central hole for wiring. Attach the light using the provided screws.
- Make Electrical Connections
Ensure power is off before connecting wires. For AC models, connect the black leads to the phase side of the incoming and outgoing power, the white leads to the common side, and the green/yellow lead to earth ground. For DC models, connect the red leads to the positive side and the black leads to the negative side, observing polarity.
- Test the Installation
After completing the wiring, turn the power back on and test the light to ensure it operates correctly. Verify that all connections are secure and that the light is functioning as intended.
- Finalize Installation
Once testing is complete, ensure all screws are tightened and provide a copy of the instruction sheet to operating personnel. Establish a routine check procedure for the light installation.
