This kind of controller works only under DC5V-24V, which is provided by the matched controllable main power, or else the controller will be damaged. 2. The UTP wire is connected hand in hand to make the cable, when two or more controller connected. 3. The power supply should be off when connecting the electric wires, and it can be turned on till making sure the wires are connected correctly and the indicator of main power in red is lighting. 4. Controller should work under the environment of adequately ventilated, dry, not corroded, no flammable gas and rust. 5. Please check the wires connection regularly so that the wires of aged, rust-eaten, and damaged insulation spacer can be replaced timely.
