5. Installation Instructions

Follow these steps carefully to install your ELEGRP USB Charger Wall Outlet:

1. Turn Off Power: Locate the circuit breaker or fuse box controlling the outlet you wish to replace. Turn off the power completely to prevent electric shock. Verify power is off using a voltage tester.
2. Remove Old Outlet: Unscrew and carefully remove the existing wall plate and outlet from the electrical box. Disconnect the wires from the old outlet.
3. Prepare Wires: Strip approximately 1/2 inch (12.7 mm) of insulation from the ends of the wires if necessary. Ensure wires are straight and free of nicks.
4. Connect Wires: The ELEGRP USB Charger Wall Outlet supports both side wiring and back wiring. Refer to the diagram below for proper connections.
   • Green Screw: Connect the ground wire (bare copper or green insulated).
   • Silver Screws: Connect the neutral wire (white insulated).
   • Brass Screws: Connect the hot wire (black insulated).
   Ensure all connections are tight. For back wiring, insert the wire fully into the terminal hole and tighten the screw. For side wiring, loop the wire clockwise around the screw and tighten.
5. Mount New Outlet: Carefully fold the wires into the electrical box. Insert the new ELEGRP outlet into the box and secure it with the mounting screws.
6. Install Wall Plate: Attach the screwless wall plate over the outlet.
7. Restore Power: Turn the power back on at the circuit breaker or fuse box.
8. Test: Test both the AC outlets and the USB ports to ensure proper functionality.

7. Maintenance

To ensure the longevity and proper function of your outlet:

• Clean the surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Periodically check for any loose connections or damage. If damage is found, turn off power at the breaker and have the outlet inspected by a qualified electrician.
• Do not attempt to disassemble or repair the unit yourself.

8. Troubleshooting

If you encounter issues with your ELEGRP USB Charger Wall Outlet, consider the following:

• No Power to AC Outlets or USB Ports:
  • Check the circuit breaker or fuse box to ensure power is on.
  • Verify that the outlet is properly wired and all connections are secure (refer to Section 5).
• Slow USB Charging:
  • Ensure you are using a high-quality USB cable.
  • Some devices may have specific charging requirements. While the outlet optimizes output, extremely demanding devices might charge slower if their maximum input exceeds the port's output.
  • If multiple devices are charging simultaneously, the total output is shared, which may reduce individual port speeds.
• Device Not Recognized by USB Port:
  • Try a different USB cable.
  • Test with a different device to isolate the issue.
• Outlet Feels Warm:
  • It is normal for electrical outlets to feel slightly warm during operation, especially when charging multiple devices or high-power devices. If the outlet becomes excessively hot, turn off power at the breaker and consult a qualified electrician.
