2.产 品 详 情 资 料：
RELIANCE DC3N-12D-00-010-AI24 V直流系统电压的接地请注意SELV EN 60950或PELV EN 60904的要求。为提高电磁兼容性，提供了仪表接地。仪表接地设计在机柜内，以满足保护接地的要求。所有H41q/H51q系统均可在L接地或不接地的情况下运行。7.2.1浮动电源如果存在多个未检测到的接地故障，RELIANCE DC3N-12D-00-010-AI可能会释放故障控制信号。为了防止这种情况，在任何情况下，浮动操作时，必须提供接地故障监测系统（也参考VDE 0116）。接地故障只能通过关闭部分功能（线路分离）来定位。如果两个极都被供电给输出电路，则可以检测到接地故障。接地操作的前提条件是接地条件良好，并且有单独的接地连接（如果可能），没有外部电流流过。仅允许L负极接地。不允许将L+正极接地，因为传感器线路上的任何接地故障都会导致相关传感器超控。RELIANCE DC3N-12D-00-010-AI
Earthing of the 24 V DC System Voltage Please regard the requirements of the SELV EN 60950 or PELV EN 60904.To improve the electromagnetic compatibility an instrument earth is provided. The instrument earth is designed within the cabinat in such a way that it fulfils the requirements of a protection earth. All H41q/H51q systems can be operated with earthed L- or not earthed. 7.2.1 Floating Supply With several undetected earth faults faulty control signals may be released. RELIANCE DC3N-12D-00-010-AITo prevent this, with floating operation in any case an earth fault monitoring system must be provided (ref. also to VDE 0116). An earth fault can only be located by switching off a partial function (separation of lines). If both poles are feed to supply an output circuit an earth fault can be detected.Earthed Operation It is prerequisite that the earthing conditions be excellent and there is a separate earth connection (if possible) through which no external currents flow. Only the earthing of the L- negative pole is permitted. Earthing of the L+ positive pole is not permissible, as any earth fault on the sensor line would result to an overriding of the sensor concerned.RELIANCE DC3N-12D-00-010-AI
