Boyin digital textile printing machine as a large high-tech equipment, in order to ensure its normal and stable operation, and effectively prevent static electricity, leakage and other safety problems, the correct connection of the ground is one of the essential steps, the following Boyin digital Technology Co., Ltd. after-sales team will introduce the method of digital printing machine connection ground.
Prepare tools and materials, including ground cables, ground terminals, screwdrivers, and resistance testers. And confirm that the working area has good grounding conditions, grounding resistance should meet the relevant national electrical installation specifications, usually less than 4 ohms.
First of all, find the ground terminal of the digital printing machine, which is generally located at the bottom of the machine or at the entrance of the power supply, and is a metal joint clearly marked with the ground symbol (similar to the inverted triangle containing a bar). Use a screwdriver to open the junction box and securely connect one end of the ground cable to the ground terminal. Ensure that the grounding cable is in good contact.
The ground cable at the other end must be connected to the workplace grounding system that meets safety standards. Usually on the ground bar near the main distribution box of the building, it is tightly connected with screws to ensure that the contact surface is clean and tight. After completing the above operations, use a resistance tester to test the newly connected grounding line to ensure that the grounding resistance meets the specified requirements and an effective grounding loop is formed.
It should be noted that we need to use more than 40*40mm galvanized Angle steel (or φ32mm2 round steel) 3 into the underground depth of not less than 2 meters, each distance is not less than 1 meter, and then use galvanized flat steel (50mm*5mm) to weld the 3 firmly together, and open q8mm holes at the end. The distance between the ground body and the building is not less than 2 m. Use insulated copper wire larger than q6mm2 as the lead. Secure one end to the ground body using M8 screws, and connect the other end to the ground lead of the device.
The above is the method of connecting the ground wire of the digital printing machine. It is necessary to regularly check whether the ground wire is caused by poor contact or broken line due to wear, rust and other reasons, and timely maintenance and replacement, so as to effectively avoid possible electrical safety hazards.
