7.2 安装
Installation
请安装于金属等阻燃物上。断路器可垂直安装，也可以水平安装。
Please install the breaker on flame
retardants such as metal, etc. It can be installed vertically or horizontally.
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
°
.

8.1 欠电压脱扣器 Under-voltage release
断路器带有欠电压脱扣器时，应使欠电压脱扣器先通电，断路器才允许合闸.
When the breaker has an under-voltage release, the under-voltage release should be
electrified, and then the breaker allows switch on.
根据引出的导线编号借入电源(直流电源不必区分正负极)
Power supply is accessed according to lead-out wire number(anode and cathode of DC power
supply are not differentiated).
当电源电压下降到欠压脱扣器额定工作电压的 70%～35%
范围内时，欠压脱扣器能可靠的分断断路器；当电源电压
低于欠压脱扣器额定工作电压的 35%时，欠压脱扣器能防
止断路器闭合；当电源电压高于欠压脱扣器额定工作电压
的 85%时，欠压脱扣器能保证断路器可靠闭合。
When power voltage declines to 70%～35% of the rated working
Voltage of undervoltage tripper, the undervoltage tripper can
reliably break the breaker up; when power voltage is lower than
the rated working voltage of undervoltage tripper by 35%, the
undervoltage tripper can prevent the breaker from closing; when
power voltage is higher than the rated working voltage of undervoltage tripper by 85%, the
undervoltage tripper can guarantee the reliable closure of breaker.
