Generally speaking, the steps to follow in the installation of a Tri-Proof LED Tube are as follows: The first step is to have the screen to be installed and all the necessary tools: drill, screwdriver, 6mm drill bit, 6mm dowel, screws and pliers or wire strippers. Cut off the electrical current from our main switchboard, you can remove only the lighting circuit breaker or the main switch of the area where you are going to install the luminaire. Open the luminaire and measure the distance between holes. We will look at where the installation cables are and where they enter our screen. Once we know where the connection will be made, it is time to mark on the ceiling, with a pencil, where the luminaire will be placed. We take a drill and drill the holes, then we will place the plugs. We then screw in the clamps and fit the watertight screen. We connect the cables of the luminaire to those of the electrical installation (phase to phase, neutral to neutral, etc...). They are usually the same colour. Connect the power supply and check that everything is working correctly. If for any reason it does not work, check the previous connection steps.
