HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Disconnect all power before servicing equipment.
Failure to follow these instructions will result in death or serious injury.
HAZARD OF FIRE OR ELECTRIC SHOCK (FOR CONTACTOR WITH HI-FAULT SHORT CIRCUIT CURRENT RATINGS ONLY)
p
The opening of the branch-circuit protective device may be an indication that a fault current has been interrupted.
p
To reduce the risk of fire or electric shock, current-carrying parts and the other components of the controller should be examined and
replaced if damaged.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
能有火灾或者触电的危险（仅限有高故障短路电流额定值的接触器）
p 支路保护设备断开，表明故障电流已被中断。
p 为降低火灾或触电风险，应检查带电部件和 其他控制元件，如有损坏，需及时更换。
不遵循上述说明可能导致人员伤亡或设备损坏。
电击、爆炸或弧闪的危险
在此电力设备 上进行工作时, 请先切断所有电源。
不遵循上述说明将导致人员伤亡。

M7C module. Then under low voltage (<140 Vac) or overvoltage (>280 Vac) conditions, the module will work to
protect against coil burnt.

模块后，在欠电压（<140 Vac)或过电压(>280 Vac)工况下，模块将起到保护作用，有效避免线圈烧毁。
Insert module directly to A1/A2 terminals of the contactor.
直接将模块插 接在接触器 A1/A2 端子。

Wiring diagram for self-locking / 自锁电气连接
When overvoltage or undervoltage occurs, the module protection function will be triggered, and the contactor will drop-out. They
behave as follows:

External power should be cut off after the module is triggered. The module will then restore automatically for next use after reset. Reset
the module by following methods:
p
Suggestion: use the contactor self-locking mechanism, to realize module reset automatically. Wiring circuit diagram is as follows:
p
The contactor self-locking mechanism is not used: to avoid module damaging, do not keep the module triggered for long time(<4h),
cut off the power manually in time and use module again after 30s.
在模块保护功能被触发后，需要切断控制回路电源。重置后，模块将自动恢复以便下次使用。可通过以下方式进行重置：
p
推荐：利用接触器自锁机制，实现模块自动复位，接线电路图如下：
p
未使用接触器自锁机制: 为避免模块损坏，请勿长时间（小时）触发模块，及时手动切断电源，等待秒后可以再次投入使用。
