〔8〕断市电输入开关，测试UPS后备电池的放电功能〔根据配置时间，确定放电时间〕。放电测试结束后,测量放电电流与电压,合输入开关,负载由市电经INVERTER供电,测量充电电压与电流。
〔9〕填写保养报告给用户确认。
上述维护工作中存在的风险
在对UPS进行维护的过程中，市电意外停电， UPS将无法保证负载的供电，此时负载会断电。
我们的对策：
〔1〕安全为首位；
〔2〕高效、合理地进行维护检查工作，降低风险。
〔3〕严格执行标准操作，杜绝因人为因素对用户负载产生的影响。
1．2、维修保养内容包括：
环境检查：
1) 房间的清洁程度。
房间的温度：电池房〔小于25度〕、UPS房〔小于40度〕。
设备四周及上面是否有堆积物。
房间的空调通风情况。
设备上方是否有水管。
是否所有金属柜、架都有地线连接。
输入滤波器检查：
物理检查：
