Notes 1.The thickness of the wires shall be adopted based on the possible current,products power,length of the wire extention(5meter at maximum as recommended) and the loss in the wirestransit at low voltage. 2.The both ends of extention shall be dealed with as waterproof. 3.Don't work under the situations of touching in static-electronics environments or light on. 4.The modules can be connected to 5m at maximum and no exceed. 5.Suggest choosing high-qualited switch power( have shortelectronics ,overvoltage andoverloading protection function etc).
