AC frequency conversion power supply use precautions

Precautions for the construction of home improvement wires into the wall:

1. When installing home electric wire into the wall, it must be buried with flame-retardant pvc bushing. The wire inside the pipe can be replaced. The spacing of the bushing is fixed at 500mm, the surface of the bushing is 13mm or more below the wall surface, and the wire in the pipe cannot be connected. Not more than 40% of the pvc pipe diameter; pay attention to the wall wire to the square (not obliquely);

Note: Before the casing is closed, it is necessary to check whether the wire is connected and test its insulation performance.

2. When laying the concealed pipe route, try to lay along the nearest specification, and strive to make the pipeline the shortest, not crossover, and there must be no junction box jump pipe;

Note: When the concealed pipe is connected to the connection box, cassette, and switch socket box, the interface must be secure.

3. After the home improvement wire is inspected by the wall, the wall is wetted, closed with 1:5 ,, the surface is required to be flat and 2mm below the wall surface;

Note: If the circuit is re-arranged, the circuit layout should be drawn for future maintenance. In addition, it should be noted that the strong and weak electricity cannot be co-slotted, and the minimum spacing between the two is kept at 300mm.

When installing the outlet switch, the safety switch is the first and convenient to apply.

1 The bottom edge of the switch box is 1.2-1.4m from the ground, and the side edge line should be more than 7cm. The same room must be the same; the same type of switch socket is installed side by side, the height difference from the ground is not less than 1mm, the whole set of room-mounted switch socket The height difference should not be greater than 5mm, and the same room must be consistent;

2 The installation of the lamp switch must be connected in series on the phase line, and must not be connected in series on the zero line;

3 Sealed protective socket switch is applied in wet places, and the installation height is not less than 1.5m.
