使用和维护/ Application & Maintenance
9.1 欠压脱扣器 Under-voltage release
断路器带有欠压脱扣器时，应使欠电脱扣器先通电，断路器才允许合闸。
If the breaker has the Under-voltage release, the Under-voltage release should be electrified
before breakers can be closed.
(1)根据外挂欠电压模块上的接线端子编号接入电源（直流电源不必区分正负极）
。
(2)在额定控制电源电压的 35%-70%时，欠压脱扣器应可靠使断路器脱扣；
(3)在额定控制电源电压的 85%-110%时，欠压脱扣器应保证断路器能合闸；
(4)在额定控制电源电压低于 35%时，欠压脱扣器应防止断路器合闸。
(1)Power supply is connected to the release according to wiring terminal number of the add-on
Under-voltage module (no need to distinguish positive and negative for direct current).
(2)At rated control supply voltage of 35%-70%, Under-voltage release should be reliable to
trip breakers. (3)At rated control supply voltage of 85%-110%, Under-voltage release should
be able to close breakers.
(4)At rated control supply voltage less than 35%, Under-voltage release should prevent
breakers from
closing.
9.2 分励脱扣器 Shunt release
根据引出的导线编号接入电源（直流电源不必区分正负极）。当分励脱扣器的外加电压介于额定控制
电源电压的 70%-110% 之间时，能可靠分断断路器。
Power supply is connected to the shunt release according to outlet wire number (no need to
distinguish positive and negative for direct current). At rated control supply voltage of 70%-110%,
shunt release should be reliable to trip breakers.
