4. Setup and Installation
Before beginning installation, ensure all power is disconnected at the main circuit breaker. Refer to the wiring diagrams below for correct connections. This ballast is designed for professional installation only.
4.1 Wiring Connections
The ballast features clearly marked terminals for input power and lamp connections. Follow the diagram precisely to ensure safe and correct operation.
Figure 4.1: Detailed wiring diagram illustrating connections for two compact fluorescent lamps to the electronic ballast. Terminals 1, 2, 3, 4, 5, 6, 7 are shown for lamp connections, along with main power input (220-240V) and protective earth (PE).
- Power Input: Connect the main power supply (220-240V) to the designated input terminals. Ensure proper phase and neutral connections.
- Protective Earth (PE): Connect the protective earth conductor to the PE terminal.
- Lamp Connections: Connect the two fluorescent lamps to terminals 1-7 as indicated in the diagram. Pay close attention to the specific connections for each lamp.
- Wire Preparation: Use wires with a cross-section of 0.5-1.5 mm². Strip the wire insulation to a length of 7.5-8.5 mm before inserting into the terminals.
- Lead Lengths: For terminals 1, 2, 3, 5, the maximum lead length is 2 meters. For terminals 6, 7, the maximum lead length is 1 meter.
4.2 Mounting
Mount the ballast securely within the lighting fixture or enclosure. Ensure adequate ventilation to prevent overheating. Refer to the dimensional drawing for physical dimensions.

5. Operating Instructions
Once correctly installed and wired, the Osram QUICKTRONIC® MULTIWATT ballast operates automatically. Upon applying power, the ballast will initiate the connected fluorescent lamps with optimal filament preheating, ensuring a gentle start and maximizing lamp life. The ballast maintains stable lamp operation throughout its use.
- Power On: Apply power to the lighting circuit. The lamps should illuminate immediately.
- Dimmable Functionality: If connected to a compatible dimming system, the ballast will respond to dimming commands to adjust light output. Ensure both the ballast and lamps are rated for dimming.
6. Maintenance
The Osram QUICKTRONIC® MULTIWATT electronic ballast is designed for maintenance-free operation. However, periodic inspection of the lighting fixture and its components is recommended.
- Cleaning: Disconnect power before cleaning. Use a dry, soft cloth to wipe the exterior of the ballast if necessary. Do not use liquid cleaners or solvents.
- Inspection: Periodically check wiring connections for tightness and signs of wear or damage. Ensure the ballast is free from dust accumulation that could impede heat dissipation.
- Lamp Replacement: When replacing lamps, ensure power is off. Use only compatible fluorescent lamps as specified for this ballast (2x26-42W).
7. Troubleshooting
If you experience issues with your lighting system, refer to the following troubleshooting steps. Always disconnect power before performing any checks or repairs.
| Problem | Possible Cause | Solution |
|---|---|---|
| Lamps do not light up. | No power supply, faulty lamps, incorrect wiring, faulty ballast. | Check circuit breaker. Verify power to the fixture. Replace lamps with known good ones. Inspect wiring connections for correctness and tightness. If problem persists, ballast may be faulty and require replacement. |
| Lamps flicker or dim unexpectedly. | Loose connections, incompatible lamps, unstable power supply, ballast nearing end of life. | Check all wiring connections. Ensure lamps are compatible with the ballast's wattage range. Verify stable power supply. If issue persists, consider replacing the ballast. |
| Ballast makes unusual noise or emits smoke/odor. | Internal fault, overheating, short circuit. | Immediately disconnect power. Do not attempt to operate. Replace the ballast. This indicates a serious malfunction. |
