Setup and Installation
Safety First: Always disconnect power at the circuit breaker before installing or servicing the driver. Installation should be performed by a qualified electrician in accordance with national and local electrical codes.
- Mounting: Securely mount the driver in a suitable location. The NEMA 4X enclosure allows for wet location installation, but ensure proper ventilation and access for wiring.
- Wiring Input (AC): Connect the AC input wires (Line, Neutral, Ground) to the designated terminals within the input compartment. Ensure all connections are tight and secure.
- Wiring Output (DC): Connect the 24VDC output wires to your compatible Nora Lighting 24V system or LED fixtures. Observe polarity (+ and -).
- Dimmer Connection (if applicable): If using a compatible dimmer, connect the dimmer control wires (e.g., 0-10V, PWM) to the appropriate terminals on the driver. Refer to your dimmer's instructions for specific wiring diagrams.
- Enclosure Closure: Once all wiring is complete and verified, securely close the driver's compartments.
- Power On: Restore power at the circuit breaker and test the system.
Note: The driver features separate compartments for input and output wires to facilitate organized and safe wiring practices.
Operating Instructions
The Nora NPSU-60W/24 driver operates automatically once properly installed and powered. It converts incoming AC power to a stable 24VDC constant voltage output for your LED lighting system.
- Power On/Off: Control the power to the connected lighting system via the main power switch or circuit breaker.
- Dimming: If a compatible dimmer is connected, use the dimmer control to adjust the light output from 1% to 100%. The driver is designed for stable, flicker-free dimming.
- Compatibility: Ensure that the connected LED fixtures or systems are rated for 24VDC constant voltage and do not exceed the driver's maximum wattage (60 Watts for this model).
Maintenance
The Nora NPSU-60W/24 driver is designed for long-term, maintenance-free operation. However, periodic checks can ensure optimal performance:
- Cleaning: Ensure the driver's exterior is free from excessive dust or debris. If cleaning is necessary, disconnect power and use a dry, soft cloth. Do not use liquid cleaners.
- Connections: Periodically check all wiring connections for tightness, especially after initial installation or if any issues arise.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges. Although rated for wet locations, avoid direct submersion or extreme conditions beyond its rating.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No light output | No power to driver; Loose wiring connections; Overload; Faulty LED fixture. | Check circuit breaker and power supply; Verify all wiring connections; Ensure total wattage of connected LEDs does not exceed 60W; Test LED fixture with another known good driver. |
| Flickering or unstable dimming | Incompatible dimmer; Dimmer not properly wired; Minimum load not met. | Ensure dimmer is compatible (Triac, ELV, MLV, 0-10V, PWM); Check dimmer wiring; Ensure sufficient load is connected to the driver. |
| Driver overheating | Insufficient ventilation; Overload; Ambient temperature too high. | Ensure proper airflow around the driver; Reduce connected load; Verify ambient temperature is within specifications. |
If troubleshooting steps do not resolve the issue, contact Nora Lighting customer support or a qualified electrician.
