1、 Pay attention to the arrangement of external wires of various devices to prevent incorrect polarity installation. The device should not be too close to the heating element, and the working conditions should not exceed its specified limits.
2、 Do not install LEDs with deformed pins.
3、 When deciding to install in the hole, calculate the size and tolerance of the hole spacing on the face and circuit board to avoid excessive pressure on the bracket.
4、 When installing LED lighting fixtures, it is recommended to use guide sleeves for positioning.
5、 When installing LED lighting fixtures, special attention should be paid to connecting the live and neutral wires.
6、 Due to the use of low-voltage DC power supply for LED lighting fixtures, if it comes with a power supply, it can be installed directly. If the blade is broken and there is no power supply, a power output port needs to be connected. Of course, most LED lighting fixtures come with their own power supply, so they can be installed directly like regular lighting fixtures. It should be noted that LED tubes have their own power supply, so when using LED tubes, it is necessary to remove the traditional starter and rectifier, which are useless.
