WE-M8-DC
【Attentions】
This device must be installed by qualified electrician, and is not allowed to open device;
Don’t operate device with wet hands, otherwise, electric shock may occur;
This device is not have waterproofed ,do not use it in humid environment；
The safety lock should be pulled out while installation；
This device will enter “LOCK” mode while circuit has fault of overload, short circuit or manually switch off. The unlock process is to manually pull out the safely lock, identify and solve the circuit fault problem. Release safety lock, and manually switch off/on once, it will work.
1. Product description
WE-M8-DC series is a compact smart circuit breaker for intelligent and safe electricity applications. The local communication adopts the MODBUS RTU protocol, which has strong versatility. Local or remote centralized control of 100A and below is possible.
1.Remote control: This product can realize local 485 communication control and configuration equipment, no need to configure professionals
2. Safe use of electricity: Fully combine the safety of circuit breakers and the intelligence of electronic products, with over-voltage/short-circuit/overload protection, and automatically trip after detecting line faults.
3. Timing control: multiple time points can be set (default 4), timing on and off.
4. Metering function: Built-in multi-function electric meter function, realizing the measurement of current and electric energy, and the accuracy of electric energy measurement is level 1.
5. Working power supply: DC48V power supply, which can directly control DC equipment.
6. Compact height: small size, 18mm width of the implementation body, standard 35mm guide rail, easy installation.
7. Firmware upgrade: Support online upgrade via RS485, which facilitates maintenance of product function updates. 8. Safe and reliable: Equipped with machine body inspection and repair device, which is convenient for local maintenance.

4. Product Installation Instructions
5. Fault Reminder Description
Description of the problem | The device cannot communicate, send opening/closing command, no action
|
Solution | Please ensure that the device is in normal operation, and then check whether A and B of the RS485 line are reversed, whether the communication configuration is correct, and whether there is any abnormality in the communication connection
|
Description of the problem | The device cannot close the gate
|
Solution | Please ensure that the device is in normal operation mode, and then check whether the device has short circuit, overcurrent and other faults. After the fault is eliminated, it can work normally after manual closing after 1 minute
|
Description of the problem | After the power is turned on, the indicator light does not light up |
Solution | Check whether the power interface is reversed and whether the output of the switching power supply has power. |
