2.產(chǎn) 品 詳 情 資 料：
RELIANCE DC3N-12D-00-010-AI24 V直流系統(tǒng)電壓的接地請注意SELV EN 60950或PELV EN 60904的要求。為提高電磁兼容性，提供了儀表接地。儀表接地設(shè)計在機柜內(nèi)，以滿足保護接地的要求。所有H41q/H51q系統(tǒng)均可在L接地或不接地的情況下運行。7.2.1浮動電源如果存在多個未檢測到的接地故障，RELIANCE DC3N-12D-00-010-AI可能會釋放故障控制信號。為了防止這種情況，在任何情況下，浮動操作時，必須提供接地故障監(jiān)測系統(tǒng)（也參考VDE 0116）。接地故障只能通過關(guān)閉部分功能（線路分離）來定位。如果兩個極都被供電給輸出電路，則可以檢測到接地故障。接地操作的前提條件是接地條件良好，并且有單獨的接地連接（如果可能），沒有外部電流流過。僅允許L負極接地。不允許將L+正極接地，因為傳感器線路上的任何接地故障都會導(dǎo)致相關(guān)傳感器超控。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
