Installation considerations
1. Make sure the electricity is turned off before installation. It is completely forbidden to operate when electrified.
2. It is advised to connect a circuit breaker or fuse in series with the surge protection module's front end.
3. During installation, adhere to the installation schematic for connection. Steer clear of bad connections. Close the circuit breaker (or fuse) switch after installation, then make sure everything is operating normally.
4. After installation, make sure the surge protection module is operating properly by putting it in place.
5. Check the condition of the fault display window and conduct routine inspections of the surge protection module while in use. The surge protection module needs to be changed or repaired right away if the fault display window turns red or if the remote signaling terminal emits an alert signal.
6. It is recommended to install parallel-connected power surge protection devices. The connection wires need to be straight, short, thick, dependable, and secure.
