procedures:
（1）用 500 Vdc 兆欧表；
(1) Use a 500 Vdc megameter；
（2）在断路器处于断开状态，对进出连接板 1-2、3-4、5-6 之间，和 1、3、5 连接板（3 个连接板
用导线相连）与外壳之间（外壳用金属箔覆盖）分别进行；
(2) Place the breaker in open status, carry out test between 1-2, 3-4 and 5-6 connection boards,
as well as between the 1, 3 and 5 connection boards (connected with wires) and the breaker shell
(covered by metal foil)；
（3）对接至主电路的分励脱扣器，在进线与断路器外壳间；
(3) Test should be done in position between incoming wire and breaker shell to test shunt release
in the main circuit；
（4）绝缘电阻不小于 12MΩ。
(4) Insulation resistance should not be lower than 12MΩ.
6.2 安装方式 Mounting method
请安装在如金属等阻燃物上。断路器可垂直安装见下图 3，也可以水平安装见下图 4。Please
install the breaker on flame retardants such as metal, etc. It can be installed vertically is shown as
follow Fig. 3 or horizontally is shown as follow Fig. 4.
产品垂直安装时，安装面与垂直面的倾斜角度≤±22.5°。When the product is installed vertically,
the angle of inclination between the installation surface and vertical surface shall be ≤±22.5°.
7 附件说明 Accessory
