⑨对于两个控制站之间或控制站与操作台之间的距离较远的情况下（一般以是否在同一幢内或者两者之间距离超过3Om为基准)，可以采取分别接地的原则进行接地。若远程机笼与主控机笼之间采用了电气隔离装置或光电隔离装置，则远程机笼可以就地进行接地。
UPS的接地一般应选择厂方的电气地。
接地系统接线和接地电阻
1、接地系统的导线应采用多股绞合铜芯绝缘或电缆。
2、接地系统的各接地汇流排可采用截面为25mm×6mm 的铜条制作。
3、接地系统的各接地汇总板应采用铜板制作，厚度不小于6mm，长、宽尺寸按需要确定。4、机柜内的保护接地汇流排应与机柜进行可靠的电气连接。
5、工作接地汇流排、工作接地汇总板应采用绝缘支架固定。
6、接地系统的各种连接应牢固、可靠，并应保证良好的导电性。接地线、接地干线、接地总干线与接地汇流排、接地汇总板的连接应采用铜接线片和镀锌钢质螺栓，并应用防松件，或采用焊接。

⑨ For situations where the distance between two control stations or between the control station and the control console is relatively long (generally based on whether they are in the same building or if the distance between the two exceeds 3 meters), the principle of separate grounding can be adopted. If an electrical isolation device or photoelectric isolation device is used between the remote cage and the main control cage, the remote cage can be grounded locally.
The grounding of UPS should generally choose the manufacturer’s electrical grounding.
Grounding system wiring and grounding resistance
1. The conductors of the grounding system should be insulated with multi stranded copper cores or cables.
2. The grounding busbars of the grounding system can be made of copper bars with a cross-section of 25mm x 6mm.
3. The grounding summary boards of the grounding system should be made of copper plates with a thickness of no less than 6mm, and the length and width dimensions should be determined as needed. 4. The protective grounding busbar inside the cabinet should be reliably electrically connected to the cabinet.
5. The working grounding busbar and the working grounding summary board should be fixed with insulated brackets.
6. The various connections of the grounding system should be firm, reliable, and ensure good conductivity. The connection between the grounding wire, grounding main line, grounding main line, grounding busbar, and grounding summary board should be made of copper connectors and galvanized steel bolts, and anti loosening parts or welding should be used.
