Matters needing attention:
1 do not connect the input and output terminals, so as to avoid the bad LED power supply.
2 LED waterproof power supply case ground wire (FG) must be grounded in order to ensure the safety; non error will be connected to the ground wire (FG) on the zero line.
3 LED power must be used in a suitable environment, working in harsh environments is likely to shorten the life of the power supply.
4 in order to achieve the best cooling effect, the LED power supply is recommended to install the air flow in a good location, or installed in the metal chassis.
5 please correctly match the power supply with the light source, so as to avoid the lamp can not work properly or damaged lamps and power supply, resulting in loss of.
