Since the laser cutting machine has high-power lasers, power converters and sensors such as electromagnetic filters, all these components can produce electromagnetic interference to a certain extent.

In order to ensure the stability of the equipment and minimize electromagnetic interference, and to avoid a series of failures caused by these disturbances, laser cutting machine manufacturers require enterprises to meet the following requirements:

1、 The voltage is 220V. If the voltage is out of range or unstable, a stabilizer should be installed;

2、 The power socket must comply with the standard live wire, neutral wire and ground wire standards;

3、 The following reliable grounding wire measures shall be provided:

(1) First find wetlands around the house and dig 1.5 × 3 square meters of deep pit, then use 1500mm angle steel to insert into the soil, use electrical welding 330mm flat iron or 8mm screws to connect the conductive elements around the screws, tighten the nuts and bury firmly, and the exposed part should be 2m higher than the ground.

(2) After the grounding is completed, the resistance of the grounding wire measured by the instrument shall be less than 5 ohms.

(3) Use resistance measurement, use 2.5 filament head on the ground, and the socket connected to the ground is required by other end users' electrical equipment.

(4) Replace the common leakage protector with a slightly larger leakage protector.

(5) Install leakage free short circuit protector.

(6) Install the transformer in the power house.

4、 For large fans and coolers with power greater than 750W, a separate socket shall be used for power supply.
