When Installing A Class I Surge Protector, Attention Should Be Paid To The Wiring Method.

During thunderstorms, without a surge protective device installed, household electronics may experience overvoltage damage, potentially leading to fire hazards. However, many people are not fully familiar with surge protector installation. What issues should be considered when installing this device?

Wiring Direction

A crucial and fundamental aspect of installation is the wiring direction. The input and output terminals must not be reversed; otherwise, the effectiveness will be significantly affected, and the device may even fail to function properly.

Wiring Method

There are two main wiring methods for surge protectors: series and parallel. Series connection is typically used only for terminal connections; parallel connection is used in other situations. When wiring, ensure the phase wire is connected to the "L" terminal of the surge protector, the neutral wire to the "N" terminal, and finally, the wire is led out from the "PE" terminal and connected to the busbar.

Grounding Wire Connection

When grounding, the length should be as short as possible. One end can be connected to the equipment's wiring terminal, and the grounding wire should be connected to an independent grounding network.

Installation Location

The installation location of the primary surge protector is also important. Typically, a graded protection method is used, and it is installed in the main distribution cabinet. In addition to the primary surge protection device, attention should also be paid to the installation of secondary and tertiary surge protectors. The installation location must ensure that there are no flammable or explosive materials.

These are the installation precautions for primary surge protectors. You can refer to them when installing. If you are unable to do it yourself, you can find a professional to do it.
