THISIS TO MAKE SURE THAT A POSSIBLE MAINTENANCE ERROR ON ONESYSTEM IS NOT DONE AGAIN ON A DIFFERENT SYSTEM. A MAINTENANCEERROR ON MORE THAN ONE HYDRAULIC SYSTEM CAN CAUSE SYSTEMFAILURE ON MULTIPLE SYSTEMS. IF MAINTENANCE IS NECESSARY ONMORE THAN ONE SYSTEM AT THE SAME TIME AND INVOLVES LINES /COMPONENTS DISCONNECTION, DIFFERENT MAINTENANCE PERSONNELMUST BE USED FOR EACH SYSTEM.注 意: 遵守以下预防措施，使得电线处于一种安全状态（电气和机械可用状态）。当你在做维护工作的时候，修理或者改装，保持导线束，部件和工作区域尽可能的干净。执行以下步骤： 执行保护措施，比如塑料布，棉布等导线束和部件上必须的保护措施。 均匀的除去所有毛边，不需要的材料和其他污物。 参考ESPM20-55-00，这些预防措施能减小需安装导线束的污染和损坏的风险。CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP ELECTRICALWIRING IN A SATISFACTORY CONDITION (ELECTRICALLY ANDMECHANICALLY SERVICEABLE).WHEN YOU DO MAINTENANCE WORK, REPAIRS OR MODIFICATIONS,ALWAYS KEEP ELECTRICAL WIRING, COMPONENTS AND THE WORK AREA AS CLEAN AS POSSIBLE. TO DO THIS :- PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC., ASNECESSARY ON ELECTRICAL WIRING AND COMPONENTS.- REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL ANDOTHER CONTAMINATION.THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATIONAND DAMAGE TO THE ELECTRICAL WIRING INSTALLATION.IF THERE IS CONTAMINATION, REFER TO ESPM 20-55-00.A.通用信息/GENERAL(1) 标准施工/ Standard Practices(a) 对于本EO中所提供材料的规格，参考CML。 For the specification of materials (Mat.
