How are solar cell modules fixed?

How to fix the solar cell module? The solar cell module and the battery module bracket are fastened with M6×20 bolts, M6 nuts and washers 6 . When installing, the bolts should be installed from the outside to the inside, and then put on washers and tighten with nuts. When tightening, the bolt connection should be firmly connected without loosening. Install the light fixture (with light source installed inside, for Regal fish and Fumei fish type light fixtures): 1) Turn on the light fixture, loosen the bolt with the Allen key of M10 (Regal fish light fixture) or M8 (Fume fish light fixture), and then put the lamp head Insert it into the light pole, adjust the direction of the light head and fasten the bolt. 2) The positive and negative poles of the source wire are connected correspondingly. When the light source is an electrodeless lamp, for a single lamp head dual light source lamp, one way is connected to the terminal at the end of the lamp head. For the current connection, the red wire is required to be connected to the L terminal, and the blue wire is required to be connected to the N terminal; for a single lamp head single light source lamp, the light source wire is connected to the terminal at the tail of the lamp head, and the red wire is required to be connected to the positive terminal, and the blue wire is required to be connected to the negative terminal. When the light source is an energy-saving lamp, the light source wire should be connected to the terminal at the end of the lamp head, and the red wire should be connected to the positive electrode, and the blue wire should be connected to the negative electrode. Finally, the lamp head should be covered. For single lamp head dual light source lamps, wiring should be made according to the working time of the light source.
