Kerien Automation Co., Ltd. is located in the beautiful coastal city-Xiamen, Fujian, China. It is one of the beautiful coastal tourist cities in Southeast China.
We are a supplier of industrial automation parts. We focus on PLC modules and DCS cards, and undertake PLC control cabinets and inverter control cabinets. The brands are as follows: 

Invensys Foxboro,Invensys Triconex,Rockwell Allen-Bradley Relianc,Schneider Modicon,ABB,Siemens,GE FANUC,Yaskawa,Bosch Rexroth,Westinghouse,Woodward,Ovatin...etc.

The grounding screw is insulated due to the rubber between the cabinet body and the base, and the shielding busbar is insulated from the base. The field control station shall be grounded according to the regulations. That is, they are respectively connected to the grounding busbar of the field control station. The power ground of I/O cabinet and UPS are connected to the same ground to ensure equipotential. 2. Each hardware equipment operator station, engineer station, network switch, server host, system display, etc. shall be grounded by shell or directly connected to the electrical grounding grid. 3. The 40 terminal of the analog module of the I/O module, namely the negative terminal of DC 24V, is connected to the logic grounding bus, the logic grounding bus is connected to the shielding ground, and then connected to the general grounding bus. 4. Shielding ground The protective ground of the field control station shall be connected from the grounding screw under the cabinet to the grounding branch line, and the shielding ground of the field control station shall be connected from the grounding bus bar to the public connection board. 5. Grounding resistance test The resistance of the grounding system shall be tested to ensure that the grounding can meet the requirements of the control system manufacturer. 1 The shell, instrument panel, cabinet, box, box, cable trough, protective tube, support, base and other normal and uncharged metal parts of the electrical instrument that may have dangerous voltage due to insulation damage shall be grounded for protection. For local instruments and switches with power supply voltage not higher than 36V, protective grounding is not required when there are no special requirements in the design documents.
