- Install sufficiently dimensioned equipotential bonding lines if high potential differences between the system components are present or expected to occur with your specific application
- 如果系统组件之间存在，或者预计在特定应用中存在高电位差，安装尺寸足够大的等电位连接线。
- The impedance of the equipotential bonding line should amount to maximum 10% of the shield impedance of shielded signal lines between the same points.
- 等电位键合线的阻抗应达到相同点之间屏蔽信号线屏蔽阻抗的最大10%
- The cross-section of the equipotential bonding line must be rated for the maximum compensating current. Experience has shown that a cross-section of 16 mm² is usually sufficient
- 等电位键合线横截面的额定电流必须达到最大补偿电流。经验表明，16mm²的横截面通常就足够了
- Equipotential bonding and shielded signal cables should be laid as close as possible to each other to prevent the formation of inductive loops and the risk of interference coupling
- 等电位键合和屏蔽信号电缆应尽量靠近敷设，防止形成感应回路和干扰耦合的危险
- Ensure low-impedance connection between equipotential bonding lines and PE.
- 确保等电位键合线与PE之间的低阻抗连接
