Power Disconnection: Turn off power to the fixture at the circuit breaker. Verify power is off using a voltage tester.
Mounting: Securely mount the new ballast inside the fixture using appropriate fasteners.
Input Power (Line Voltage):
- Connect the Black wire from the ballast to the incoming Line (Hot) wire from the power supply.
- Connect the White wire from the ballast to the incoming Neutral wire from the power supply.
- Connect the Green wire from the ballast to the fixture's Ground.
Lamp Connections (Output Wires):
- For Lamp 1: Connect the Blue wire(s) from the ballast to one end of the first lamp's tombstone (socket). Connect the Red wire(s) from the ballast to the other end of the first lamp's tombstone.
- For Lamp 2: Connect the Yellow wire(s) from the ballast to one end of the second lamp's tombstone. Connect the Orange wire(s) from the ballast to the other end of the second lamp's tombstone.
- Note: Some ballasts may have multiple wires of the same color for each lamp connection. Ensure all wires for a specific connection point are properly grouped and secured. Refer to the ballast's specific wiring diagram.
Secure Connections: Use wire nuts or approved connectors for all wire splices. Ensure all connections are tight and insulated.
Lamp Installation: Install the compatible fluorescent lamps into the fixture sockets.

7. Troubleshooting

If your fluorescent fixture is not operating correctly, refer to the following troubleshooting guide:

Problem	Possible Cause	Solution
Lamps do not light up.	No power to the fixture. Loose or incorrect wiring. Defective lamps. Defective ballast.	Check circuit breaker and wall switch. Verify all wiring connections are secure and correct (refer to Section 4.2). Replace lamps with known good ones. If lamps are good and wiring is correct, the ballast may need replacement.
Lamps flicker or dim.	Old or failing lamps. Loose lamp connections. Incorrect lamp type.	Replace lamps. Ensure lamps are seated firmly in sockets. Verify lamps are compatible with the ballast (F54 T5 HO, FC40T5, F55W/2G11, F50/2G11).
Humming noise from fixture.	Loose ballast mounting. Ballast nearing end of life.	Ensure ballast is securely mounted. Consider replacing the ballast if noise persists and is excessive.

If troubleshooting steps do not resolve the issue, contact a qualified electrician or Sunlite customer support.
