Operation steps of ground wire of engraving machine

As for the power consumption of engraving machines, what you often mention is the grounding problem. Sometimes if you don't connect to the ground, there will be many unexpected problems! Remind customers to pay attention to whether their power plug-in has a grounding wire, although the problem is small, the impact is really big! Engraving Machine Manufacturers Share the grounding wire operation step 1, prepare 3 3*30 long 2. For angle steel of 5 meters, dig 3 pits with a depth of 30 centimeters on the ground at intervals of 3 meters, and then pile the angle steel into the ground. Then use 3*30 hot-dip galvanized flat steel to connect them with electric welding, and the welding is required to be lapped. 2. Measure the ground resistance of the net with a measuring instrument. The resistance is zero or below 4 ohms and can reach below 4 ohms, indicating that the grounding device is qualified. You can safely draw the grounding wire from above. 3. Drill a 8mm hole at the top of the lead-out flat iron, file around the hole, and then tighten the wire and flat iron. 4. Finally, the wire is introduced into the user's wire slot to increase a safe grounding wire in the power grid.
