Adjustable range and values
| parameter | Description | Domain | Assumption | Description | ||
| P1 | Initial setup time | 1 … 500 Second | 60 | In order to protect the equipment from the sudden disconnection and disconnection of the city’s electricity, the initial start-up time is considered, which causes the protective relay to connect with a delay when the electricity is connected. | ||
| U1 | The amount of overvoltage | 230 … 300 volt | 255 | It determines the amount of acceptable overvoltage, which according to the standard can be up to 255 volts, but the default of this device is 245 volts. | ||
| U2 | Overvoltage recovery amount | 225 … 295 volt | 250 | It refers to the voltage that allows connection after overvoltage by reaching this protective voltage, which is set to 5 volts lower than overvoltage according to the standard. | ||

Installation schematic
Installation tips:
1- It is recommended to use an expert for installation and settings
2- It is recommended to use a three-phase miniature fuse before the protector.
3- According to the figure above, the input phases should be connected to L1, L2, and L3, and the input neutral should be connected to N, and in the same way, the output neutral should be connected to the null ingot and the output phases should be connected to the input of the miniature fuses.
4- To connect the wire to the device, be sure to use the appropriate wire head
5- Make sure the connections are tight because loose connections cause heat and fire.
6- It is recommended to check the correctness of the output relay once a year by Shasti Power by disconnecting and connecting it once.

Appearance characteristic
To enter the settings page, press the SET button and after the P1 parameter appears, use the up and down arrow keys to set the value.
Change P1 parameter as desired and use the SET button to go to the next parameters.
Hold the SET button for 3 seconds to save the values.
This screen is displayed when the device is turned on. which is connected to the output of the device after the end of the countdown.
By pressing the power button as shown in the figure, the output of the device can be disconnected and connected
Note: If the output is disconnected by the user, the device starts working by disconnecting the main power and reconnecting it, and the output is connected.
Displaying this page means the error of connecting the wires of the input phase. To fix this error, phases L3 and L2 must be moved at the input. The presence of this protection causes the rotation direction of three-phase motors and pumps to change the position of the phases at the input for any reason. Do not do the opposite, which is very important.
After successive overcurrent errors occur, the protector will not connect again, and to fix this error, the device that caused the overcurrent must be turned off or the C1 parameter should be increased and restarted after resetting the device.
