2. Check the weight of lamps and lanterns. Crystal chandeliers have many lights and are very heavy. So checking the weight of the crystal chandelier is mainly to determine whether its weight can bear it. In order to ensure the safety of the crystal chandelier after installation, it is recommended that you buy and install a junction box that can support the weight of the crystal chandelier.
3. Install the hanging plate. The main purpose of installing the hanging plate is to fix the main body of the crystal chandelier and make the subsequent installation of various crystal ornaments stable. The most important thing to pay attention to in this step is to ensure that the bearing capacity of the fixing nut must match the weight of the crystal chandelier, so as to ensure that the chandelier will not fall during use after installation. After these are determined, the expansion screw can be fixed on the hole position with an electric drill bit, and the hole position cannot be offset. And in this process, keep your arms straight and don't drill holes obliquely. After drilling the hole, put the hanging plate into the expansion screw with the mounting screw in the lamp. At this time, we should pay attention to one thing, that is, do not put the screws aside first, but tighten them on both sides, so as to ensure the balance of the hanging plate.
4. Install the light bulb. After the hanging plate of the chandelier is installed, it is necessary to install the light bulb. When installing the light bulb, the wiring should be connected to the terminal of the central contact, and the zero line should be connected to the threaded terminal. When the selected lamps and lanterns adopt screw caps, the phase line should be connected in the center of the caps, and the zero line should be connected on the screws. Remember to turn on the light and do debugging when assembling the light bulb.
5. Install the crystal pendant, and after installing the light bulb, you can hang the ornaments of the crystal chandelier. Some pendants of the crystal chandelier have been installed and can be hung directly. Some need to be installed manually, and then hung in the corresponding position of the chandelier one by one. If you install crystal chandeliers yourself, it is recommended to follow the installation instructions step by step to ensure the correct installation position of each chandelier and determine the decorative performance of crystal chandeliers.
