（1）不要安装于含有爆炸气体的环境里，否则有引发爆炸的危险。
（2）请勿安装于特别潮湿的地方。
（3）不要安装在外磁场大于地磁场 5 倍的地方，否则断路器不能正常工作。
（4）不要安装在振动大于 5g 的地方。
（5）不要安装在气体介质能腐蚀金属和破坏绝缘的地方。
(1) Do not install the breaker in explosive environment, or hazard of explosion will be resulted.
(2)Do not install the breaker in extremely humid locations.
(3)Do not install the breaker in places where external magnetic field is more than 5 times of the
geomagnetic field, or the breaker cannot work normally.
(4)Do not install the breaker in places with vibration more than 5g.
