3. Product Overview
The OSRAM QTP8 1x36/230-240 is an electronic fluorescent ballast designed to power one 36-watt T8 fluorescent lamp. It provides efficient and reliable operation, ensuring instant start and stable light output for compatible fluorescent lighting fixtures. The ballast operates on a 230-240 volt AC supply.

4. Installation
Follow these steps for proper installation of the ballast:
- Power Disconnection: Ensure the main power supply to the fixture is turned off at the circuit breaker before beginning any installation work.
- Mounting: Securely mount the ballast within the lighting fixture using appropriate fasteners. Ensure adequate ventilation around the ballast.
- Wiring Connections: Refer to the wiring diagram printed on the ballast label and the general guidelines below. Use appropriate wire gauges for all connections.
- Input Power (230-240V AC): Connect the Live (L) and Neutral (N) wires from the main power supply to the corresponding input terminals on the ballast.
- Lamp Connections: Connect the lamp wires to the ballast output terminals (typically labeled 21, 22, 23, 24) as indicated by the wiring diagram for a single T8 fluorescent lamp. Ensure all connections are firm and secure.
- Verification: Double-check all wiring connections for correctness and security. Ensure no bare wires are exposed.
- Restore Power: Once installation is complete and verified, restore power to the fixture.
5. Operating Instructions
The OSRAM QTP8 1x36/230-240 T8 Fluorescent Ballast is designed for automatic operation. Once properly installed and connected to a compatible 36W T8 fluorescent lamp and power supply, the lamp will illuminate instantly upon activation of the power switch. The electronic design ensures flicker-free starting and stable light output.
6. Maintenance
This ballast contains no user-serviceable parts. Regular maintenance is limited to:
- Cleaning: Periodically clean the exterior of the ballast and fixture to prevent dust accumulation, which can affect heat dissipation. Ensure power is disconnected before cleaning.
- Inspection: Annually inspect wiring for signs of wear, damage, or loose connections. Replace any damaged components immediately.
- Lamp Replacement: Replace fluorescent lamps with compatible 36W T8 lamps when they reach the end of their life or show signs of degradation.
7. Troubleshooting
If the lamp fails to operate correctly, perform the following checks:
- No Light:
- Verify that the power supply to the fixture is active.
- Check that the fluorescent lamp is correctly seated and not faulty. Try replacing the lamp with a known good one.
- Inspect all wiring connections for looseness or damage.
- Flickering Lamp:
- Ensure the lamp is fully inserted into its sockets.
- Replace the lamp if it is old or showing signs of end-of-life flickering.
- Verify stable input voltage.
- Ballast Overheating:
- Ensure adequate ventilation around the ballast.
- Confirm the correct lamp type and wattage are being used.
If issues persist after performing these checks, contact a qualified electrician or OSRAM customer support.
