Laser cutting machines require strong power to ensure stability during operation. Due to the high voltage connection, the grounding wire is an important part of the usage process, but it is often easily overlooked. Poor grounding may lead to leakage and pose a personal safety hazard. So how about grounding work?
Be prepared before grounding:
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 three times; Every time a 30mm flat iron guide rail is used to excavate the joint, a good grounding network is formed.
When the local surface connection is completed, the grounding resistance is measured by an instrument. 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 grid and directly insert it into the grounding hole of the socket used in the laser cutting machine.
Installation steps:
Firstly, find a damp place at home, dig a soil surface of 1.5 square meters * 300 millimeters, and then use a 2 x 30 millimeter flat iron to weld or connect a 7 millimeter hole, making the ground 1.8 meters high, A clean graveyard of soil& nbsp;
2. Use measuring instruments to measure the grounding resistance of the measurement network.
3. Drill an 8mm hole at the top of the iron, drill it around the hole, and then apply a layer of pituitary gland to tighten the metal wire and flat iron.
4. Guide the wires into the user's trunking and add a safety grounding wire to the grid.
