Engraving machine ground how to do

Engraving machine grounding line! Can prevent the machine from the leakage cause shock hazard, ground to the effect of stone carving machine cannot be ignored. Also can effectively prevent electrostatic interference. Qualifies as a ground how to meet? According to the following method to operate: three 30 cm deep hole on the ground, prepare 3 root 30 long 3 * 2. 5 meters Angle. Interval of 3 meters, then put the Angle steel piling into the ground. To use 3 * 30 galvanized flat steel power holder connected, it request to lap welding. Less than 4 ohm to achieve, with measurement instrument CeLiangWang to ground resistance. Resistance to zero or below 4 ohms. Grounding device is qualified, can be at ease from the above ground wire around the hole the file clean, lead to the top of the flat iron an 8 mm holes, the conductor and the flat iron tighten again. Finally introduce the conductor wire trough of users. Increase in the power grid is one of the safe ground wire.
