3.2.1电源指示灯说明
3.2.1 description of power indicator
如果系统电压不在正常范围之内,表示电源出现故障,模块点亮FAIL灯报警,相应的5V指示绿灯和24V指示绿灯熄灭;否则,表示电源工作正常,FAIL灯熄灭,相应的5V指示绿灯和24V指示绿灯点亮。3.2.2电源开关说明
If the system voltage is not within the normal range, it indicates that the power supply has failed, the module lights up the fail light for alarm, and the corresponding 5V indicator green light and 24V indicator green light go out; Otherwise, it means that the power supply works normally, the fail light goes out, and the corresponding 5V indicator green light and 24V indicator green light are on. 3.2.2 description of power switch
按下“I”,表示开;按下“O”,表示关。
Press "I" to indicate on; Pressing "O" means off.
3.3电源的拆装
3.3 disassembly and assembly of power supply
安装时,先把电源单体滑入塑料导轨,然后把电源单体推至底,并拧紧面板上的四颗螺钉,后插接上电源背部的各接插件;拆卸时,先关闭前面的开关,拔出电源背部的各接插件,然后拧松面板上4颗螺钉,后抽出电源单体
During installation, first slide the power unit into the plastic guide rail, then push the power unit to the bottom, tighten the four screws on the panel, and then plug in the connectors on the back of the power supply; When removing, first turn off the front switch, pull out the connectors on the back of the power supply, then loosen the four screws on the panel, and then pull out the power supply unit
