4. Setup and Installation
Installation must be performed by a qualified electrician in compliance with all national and local electrical codes. Ensure power is disconnected before beginning any installation work.
4.1 Wiring Instructions
- Power Disconnection: Turn off the main power supply to the circuit where the emergency driver will be installed. Verify power is off using a voltage tester.
- Mounting: Mount the FHS2-UNV-36L emergency driver securely within the fixture or in an accessible location, ensuring proper ventilation. The unit has a rectangular aluminum housing.
- AC Input Connection: Connect the AC input wires of the emergency driver to the unswitched AC power supply (100-277V). Typically, this involves connecting the black wire to Line, white wire to Neutral, and green wire to Ground.
- Battery Connection: Connect the emergency driver to a compatible external battery backup unit (e.g., Fulham FHSBATL6-3, if applicable). Ensure correct polarity (positive to positive, negative to negative). The product description states the battery backup is not included with the FHS2-UNV-36L.
- LED Load Connection: Connect the output wires of the emergency driver to the LED load. Observe correct polarity for the LED module. The output voltage range is 11-36V DC.
- Test Switch/Indicator: If applicable, connect the test switch and charge indicator light according to the wiring diagram provided with the battery backup unit. This allows for manual testing of the emergency function.
- Power Restoration: Once all connections are secure and verified, restore power to the circuit. The charge indicator light should illuminate, indicating the battery is charging.
Note: Always refer to the specific wiring diagram provided with your complete emergency lighting system for detailed connection instructions.
5. Operating Instructions
The Fulham FHS2-UNV-36L Emergency LED Driver operates automatically. No user intervention is required during normal operation or during a power outage.
- Normal Mode: When AC power is present, the emergency driver's battery unit (if connected) will charge. The LED luminaire operates normally, powered by the standard AC supply.
- Emergency Mode: Upon interruption of normal AC power, the emergency driver automatically switches to emergency mode. It draws power from the connected battery backup unit and supplies power to the LED load, illuminating the fixture for a minimum of 90 minutes.
- Return to Normal: When AC power is restored, the emergency driver automatically returns to normal mode, and the battery unit begins recharging.
5.1 Testing Emergency Function
Regular testing is crucial to ensure the emergency lighting system is functioning correctly.
- Monthly Test: Press the test switch (if installed) for at least 30 seconds. The LED luminaire should operate in emergency mode. Release the switch; the luminaire should return to normal operation.
- Annual Test: Conduct a full 90-minute discharge test annually. Disconnect AC power to the emergency driver for 90 minutes. The LED luminaire should remain illuminated for the entire duration. After the test, restore AC power and allow the battery to fully recharge (typically 24 hours).
6. Maintenance
The Fulham FHS2-UNV-36L Emergency LED Driver is designed for minimal maintenance. However, periodic checks are recommended to ensure optimal performance.
- Cleaning: Keep the unit clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Inspection: Periodically inspect the wiring for any signs of damage, loose connections, or corrosion.
- Battery Replacement: The lifespan of the external battery backup unit varies. If the unit fails to maintain illumination for the full 90-minute duration during an annual test, the battery may need replacement. Refer to the battery manufacturer's instructions for replacement procedures.
7. Troubleshooting
If the emergency LED driver is not functioning as expected, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| LED luminaire does not illuminate in emergency mode. | No AC power to the emergency driver. Battery not charged or faulty. Incorrect wiring. Faulty LED load. | Check circuit breaker and wiring connections. Allow 24 hours for battery to charge. If problem persists, replace battery. Verify all wiring connections according to the diagram. Test LED load with a known good power source. |
| Emergency illumination duration is less than 90 minutes. | Battery not fully charged. Battery nearing end of life. Incompatible LED load. | Ensure battery has had sufficient time to charge (24 hours). Replace the battery backup unit. Verify LED load specifications are within the driver's output range. |
| Charge indicator light is off. | No AC power to the emergency driver. Faulty indicator light or wiring. Battery not connected. | Check AC power supply. Inspect indicator light and its connections. Ensure battery is properly connected. |
If troubleshooting steps do not resolve the issue, contact Fulham customer support or a qualified electrician.
