未经APC 明确同意而对设备作改动，可能使保修服务失效。
操作安全<18千克（<40磅）32-55千克（70-120磅）18-32千克（40-70磅）>55千克（>120磅）>10º小心！电气安全在危险条件下，请勿单独一人工作。
高的短路电流流过导电物质时可以造成严重烧伤。
请检查电源线、插头及插座是否完好。
只有合格的维修人员才可更换UPS 上的插头或安装永久性连接设备。
当不能确定接地情况时，为了减少触电的危险，在安装设备或与其他设备连接前，应将设备与交流电源断开。
只有当所有的连线都接好以后，才能重新接通电源。
接触任何金属接头前，务必断开电源。
连接设备时，应采用三线交流接线（两条火线，一条地线）。
插座应连接于合适的支线（或干线）保护装置（保险丝或断路器）。
采用其他类型的插座可能导致触电危险。
