57330001-Y DSBB110A 电源模块
注意事项
解决的问题保持最后状态当IC69xMDL754（-CC及更早版本）连接到单独的现场电源并配置为保持最后状态时，当机架断电时，所有输出将保持最后状态，如规定。当机架的电源恢复时，输出将瞬时关闭长达800ms，无论其最后状态如何。这些输出将返回到CPU转换到运行模式之前的最后状态。此问题已在MDL754固件的1.20版本中得到纠正。此版本问题中的已知限制和开放问题：模块的热插拔很少会触发端子块丢失/添加故障消息。建议：如果接线板存在并锁定，则忽略接线板丢失/添加故障消息。在危险场所安装标有I类A、B、C和D组2类危险场所标签的设备仅适用于I类2类A、C、D组或非危险场所警告-爆炸危险-更换部件可能会影响I类2级的适用性；警告-爆炸危险-在危险位置时，在更换或接线模块之前关闭电源；警告-爆炸危险-除非电源已关闭或该区域已知无危险，否则请勿连接或断开设备。
matters needing attention
When IC69xMDL754 (- CC and earlier versions) is connected to a separate field power supply and configured to maintain the final state, when the rack is powered off, all outputs will remain in the final state, as specified. When the power supply of the rack is restored, the output will be turned off instantaneously for up to 800ms, regardless of its final state. These outputs will return to the last state before the CPU switches to run mode. This issue has been corrected in version 1.20 of the MDL754 firmware. Known limitations and open issues in this release issue: hot swapping of modules rarely triggers terminal block loss/addition fault messages. Recommendation: If the terminal block is present and locked, ignore the terminal block missing/adding fault message. Equipment with Class I, Groups A, B, C, and D, Class 2 hazardous area labels installed in hazardous areas is only applicable to Class I, Division 2, Groups A, C, D, or non hazardous areas Warning - explosion hazard - replacement of components may affect the applicability of Class I, Division 2; WARNING - EXPLOSION HAZARD - When in a hazardous location, turn off the power before replacing or wiring the module; WARNING - EXPLOSION HAZARD - DO NOT CONNECT OR DISCONNECT THE EQUIPMENT UNLESS THE POWER IS OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS.
