  • Connect the power cord from the scene to the power cord of the lamp, connect it according to the wiring principle of the lamp, and deal with waterproofing and insulating things ;
  • Turn on the lights to see if they can work normally. After confirming the light is on, the installation is completed.

2. Bracket Installation Method:

  • Drill holes and drive-in expansion screws
  • Hang the lamp and fix the screw nut
  • Do connection by wiring diagram( Live wire/Natural wire, ground wires)
  • After all is completed, a power-on test is needed. If some lamps fail to light up, check the circuit or lamps. After ensuring that all lamps are normally lit, the installation of the LED high bay light is completed.

3. 1/2” NPT Installation Method:

  • Fix the bracket to the lights
  • Unscrew the 1/2” NPT nut

Strip a section of insulation from the two wires of the power cord to expose the copper wire. Identify the polarity of the wires: typically, the blue or black wire is the live wire, and the brown or red wire is the neutral wire. Ensure proper identification to avoid incorrect connections, connecting live wire to live wire and neutral wire to neutral wire. Then, use a screwdriver to tighten the terminal screws to ensure a good connection. After completing the wiring, wrap the stripped sections of the wires with insulating tape to prevent the wires from touching metal and causing a short circuit.

The lamp housing is connected with a PE protective wire separately for large-density lighting projects.
  4. It must be required during installation that the installer has a professional electrician certificate. 
  5. The wires on the LED lamps can be drilled through the holes and can be fixed with wire clamps through the wires behind the lamps. Make sure that the fixing is firm.
