3. Setup and Installation
3.1 Pre-Installation
- Ensure power to the circuit where the emergency light will be installed is turned OFF at the circuit breaker.
- Unpack the unit and inspect for any damage.
- Identify the mounting location (wall or ceiling) and ensure it is suitable for the unit's dimensions and weight. The unit is designed for universal J-box mounting.
3.2 Mounting Instructions
- Remove the front cover of the emergency light unit to access the mounting holes and wiring compartment.
- Position the unit against the mounting surface, aligning with the J-box or marking the drill points.
- Drill pilot holes if necessary and secure the unit's backplate to the wall or ceiling using the provided mounting hardware.
3.3 Wiring
The APEL unit supports dual voltage 120V or 277V AC input.
- Connect the AC supply wires to the appropriate terminals inside the unit. Refer to the wiring diagram located inside the unit's housing.
- Connect the black wire to the 120V AC line, or the red wire to the 277V AC line. Connect the white wire to the neutral. Connect the green wire to ground.
- Ensure all wire connections are tight and secure.
3.4 Battery Connection and Initial Charge
- Connect the Ni-Cad battery pack to the circuit board connector. Ensure the polarity is correct.
- Replace the front cover of the unit.
- Restore AC power to the circuit. The CHARGE indicator light (usually a small LED on the unit's housing) should illuminate, indicating the battery is charging.
- Allow the battery to charge for a minimum of 24 hours before performing the first test. This ensures the battery reaches its full capacity.
4. Operating Instructions
4.1 Automatic Operation
The Cooper APEL LED Emergency Light is designed for automatic operation. When AC power is present, the unit's battery charger maintains the battery at full charge. Upon an interruption of AC power, the unit automatically switches to battery backup mode, illuminating the LED heads. When AC power is restored, the unit automatically switches back to AC power, and the battery begins recharging.
4.2 Test Button
A test button is located on the unit's housing. Pressing and holding this button simulates a power failure, causing the LED heads to illuminate (if the battery is charged). Release the button to return to normal operation. This button is used for routine testing.
4.3 Adjusting LED Heads
The two LED heads are fully adjustable. Gently pivot and rotate each head to direct the light beam to the desired area for optimal emergency illumination.
5. Maintenance
5.1 Routine Testing
Regular testing is crucial to ensure the emergency light functions correctly during a power outage. Follow these guidelines:
- Monthly: Press the test button for at least 30 seconds. The LED heads should illuminate.
- Annually: Disconnect AC power to the unit for 90 minutes. The LED heads should remain illuminated for the entire duration. Reconnect AC power after the test.
5.2 Battery Care and Replacement
The Ni-Cad battery is designed for long life. If the unit fails to operate for the required duration during a test, the battery may need replacement. Contact a qualified technician for battery replacement. Use only genuine Cooper replacement batteries.
5.3 Cleaning
Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the unit is disconnected from power before cleaning.
