The remote controller of this device adopts the coding mode of 1 to 1 (i.e. the code of transmitter and that of receiver are the same, which are set as a unique code before leaving the factory). The opening and closing can be operated only after unlocking. After finishing the operation, the device will enter into the safe mode with multiple protections including locked remote operation, so as to avoid misoperation or false operation. The effective distance of remote controller is not more than 30 meters. The detailed operation of the remote controller is as follows:
If the device is opened, the steps for closing the device are: press the “Unlock” button on the remote controller to unlock the device and then press the “Close” button on the remote controller to close the device.
If the device is close, the steps for opening the device are: press the “Unlock” button on the remote controller to unlock the device and then press the “Open” button on the remote controller to open the device.
Note:
After unlocking, the opening and closing operation can be carried out continuously. If no operation is carried out for a period (about 10 seconds), the device will be locked out. Remote opening or closing can be carried out only after unlocking the device again.
2. Please refer to the instruction at the back of the remote controller of the device for the valid time of the remote controller buttons.

| Total load capacity within the user’s boundary (KVA) | <1250 | 1250-2500 | 2500-4000 | 4000-5600 | >5600 |
| Fixed value (A) | 120 | 240 | 360 | 480 | 600 |
For the system in which the neutral point is earthed by low resistance, it is recommended to choose 600A as the fixed value for phase-to-phase protection to prevent starting the phase-to-phase protection when there is an earthing fault. Fixed value for quick break is generally 3-7 times of over-current fixed value, which is subject to the actual line.
Note: This part is about the fixed values of over-current protection and earthing protection. Please skip this part if there is no fixed value for protection, e.g. pure voltage protection method.
The device adopts Chinese menu to achieve human-machine interaction. The menu structure is as shown in the following picture:
