Unpack the package, carefully read the product instruction manual, and check whether the product model and parameters are correct and whether they match the equipment. Installation must be carried out by a person with technical expertise (guidance). When installing wiring in the sun, the solar photovoltaic panels should be covered to prevent the high-voltage electric injury of the photovoltaic cells;

During installation, insert the detachable movable mounting plate (4 pieces in total) into the mounting plate socket at the bottom of the box, fix it with two M8*8 screws, and then fix it to the installation position with expansion screws.

After the photovoltaic lightning protection combiner box is connected to the photovoltaic power generation system according to the principle and installation of the wiring block diagram, the grounding end of the lightning protection box should be reliably connected with the lightning protection ground wire or busbar, and the connecting wire should be as short and straight as possible, and the cross-sectional area of the connecting wire should not be less than 16mm2 multi-strand copper core. The grounding resistance value should not be greater than 4 ohms, otherwise, the ground network should be rectified to ensure the lightning protection effect. It can only be put into use after the installation is completed and checked that it is correct.

The input and output cannot be reversed, otherwise the post-amp equipment may not work normally or even damage other equipment;

The electrical components installed in the box are specially customized products of photovoltaic lightning protection combiner box, which can not be mixed with ordinary products, if you need to replace them, please contact the seller or manufacturer, and pay attention to prevent the high-voltage electric injury of solar photovoltaic cells when replacing the fuse core (special DC high-voltage core);
