Product installation:

1. SPD is installed at the power input end of the building's main distribution cabinet or distribution box, equipped with 35mm electrical rails. Before installation, the power must be cut off and live operation is strictly prohibited.
2. During installation, SPD should be installed in conjunction with fuses of the corresponding specifications. Please connect according to the installation diagram, where L1, L2, and L3 phase wires, N is the neutral wire, and PE is the ground wire. Do not connect them incorrectly. After installation, check if the working status is normal.
3. During use, the lightning protection module should be regularly inspected and the status of the fault display window should be checked. When the fault display window is red, it indicates that the lightning protection module has malfunctioned and should be repaired or replaced in a timely manner. （Which is a good lightning protection module for three-phase power supply）
4. Suitable for indoor operation, if installed outdoors, a waterproof casing must be added.
5. All wiring must be securely and reliably electrically connected. SPD connection wire: BVR ≥ 4mm2, grounding wire: BVR ≥ 6mm2, the lead length should be less than 1m and the shorter the better.
6. Lightning protection grounding should comply with lightning protection regulations, with grounding wires as thick and short as possible and grounding resistance less than 4 Ω.
