The correct way to ground the laser cutting machine

The laser cutting machine needs strong power to ensure the stability of the work. Due to the high-voltage access, the grounding wire is an important part of the use process, but it is usually easy to overlook. Poor grounding may cause leakage and cause personal safety hazards. . So how does grounding work?

Be prepared before grounding:

1. The grounding device must be 2-4X 1500 mmX 35 degrees. It should be 1 meter away from any damp place around the house. Then use it 3 times; each time use a 30mm flat iron rail to dig the joints to form a good grounding network. .

2. When the local surface connection is completed, the grounding resistance of the grounding resistance is measured by the meter. The standard resistance is 3 to 5 ohms.

3. Display. After measuring the resistance, connect one end of the rvv2.5mm2 copper core wire to the lead end of the grounding net, and insert it directly into the grounding hole of the socket used in the laser cutting machine.

?? Installation steps:

1. First find a damp place at home, dig a soil surface of 1.5 square meters * 300 mm, and then use 2X 30 mm flat iron to weld or connect 7 mm holes to make the ground 1.8 meters high. , The soil of the net cemetery.

2. Use a measuring instrument to measure the grounding resistance of the measurement network.

3. Drill an 8mm hole on the top of the iron, punch it around the hole, and then apply a layer of pituitary gland to tighten the wire and flat iron.

4. Lead the wire into the user's wire slot, and add a safety ground wire in the grid.
