注意事项/ Notices 

10.1 安装注意事项 
(1)断路器本体、底板(板后接线用)、底座(插入式接线用)固定在安装板上。 
(2)与主电路连接 

2.1.必须由具有专业资格的人员进行配线作业。 
2.2.确认输入电源处在完全断开的情况下,才能进行配线作业。 
2.3.必须安装本体后再进行配线。 
2.4.断路器配线必须符合上进下出,即  1,3,5  端子接电源线,2,4,6  端子接负载线,不允许倒进线 

10.1Installation precautions 
  (1)Main body, baseboard (for back-panel wire connection), base (for insertion wire connection) of the 
breaker are fixed on an installation panel. 

(2) Connected to main circuit. 
2.1.Wiring operation should be carried out by professional technicians. 
2.2.Wiring operation should be carried out only when input power supply is assured completely broken. 
2.3.Wiring operation should be carried out after the main body is installed. 
2.4.In wiring operation of the breaker, wire should be inserted from the top and pulled out from the 

bottom; that is to say, terminals 1,3,5 are connected to power wire, and terminals 2,4,6 are connected to 
load wire; wiring sequence is not allowed to be exchanged. 
10.2  运行注意事项 
(1)湿手不能操作断路器,否则可能发生电击事故。 
(2)断路器不能频繁操作,否则会缩短断路器的使用寿命。 
(3)带电动操作机构的断路器脱扣跳闸后,电操机构必须使断路器再扣,然后才能合闸。 
10.2 Running precautions 
(1)Wet hand is forbidden to operate the breaker, otherwise there is electric shock hazard. 
(2)The breaker cannot be operated frequently, otherwise its service life is shortened. 
(3)If  there  are  release  and  tripping  operation  occurred  on  the  breaker  with  an  motor-operated
