远程紧急断电按钮

"REPO" 按钮用于启动系统紧急停机。 这将会断开 UPS 负载的供电。

表 1
开关技术参数    
说明     值    
导线管中的电线     18 AWG(最小)    
距 UPS 的最大距离    
152 米 (500 英尺)    
常开触点
绿色    
插针 3 和 4    
常闭触点
红色    
插针 1 和 2    

常开触点的配置

为使用紧急断电开关的常开触点,将电线从 EPO 开关的插针 3 和 4 一直布线到系统 I/O 模块上的远程输入接线板。

注: 如果未使用常闭远程开关,该对常闭触点必须被跨接以便保证正常操作。

常闭触点的配置

为使用紧急断电开关的常闭触点,拆除跨接线并从 EPO 开关的插针 1 和 2 一直布线到系统 I/O 模块上的远程输入接线板。

注: 系统 I/O 模块位于左侧部件面板的左下角。 请参阅系统操作, "接口"手册。

静态旁通开关

该选项确保在出现灾难性的内部故障或 UPS 过载事件时,从正常操作向旁通操作进行不中断转换。 可控硅整流器(SCR)用于立刻将旁通电源与输出连接起来。 于是输出接触器被命令断开,旁通接触器被命令闭合。 这将导致先接后断的开关操作方式。

注: 旁通接触器与静态开关并联。

保养旁通

旁通选项使系统能够被彻底隔离,以便在 UPS 上进行保养,同时又不会中断向负载供电。

四线输入和输出(480 伏 60 Hz)

该选项在需要中线连接时选用。

三线输入和输出(380 – 415 伏 50/60 Hz)

此选项可在负载由配电变压器馈电时选用。

备用套件

该选项提供一套用于修理 UPS 的备用零件套件。

地震栓系

该选项提供栓系支架,以便将单模块系统牢固固定到地板上。
