Section 4: Product Installation Instructions:
1. Power must be cut off before installation, and operation with power on is strictly prohibited.
2. It is recommended to connect a fuse or a circuit breaker in series at the front of the lightning protection module.
3. SPD is paralleled installed at the power input end of the building's distribution box or the equipment room. The product features a track-mounted installation, and a Kevin connector type may be used under permissible conditions.
4. Please connect according to the installation diagram provided, where L stands for phase wire, N for neutral wire, and PE for ground wire. Do not connect them incorrectly. After installation, close the automatic circuit breaker switch and check if the operation is normal.
5. During use, the lightning protection module should be regularly inspected and the status of the fault display window checked. If the fault display window shows red or if the remote signal terminal outputs an alarm signal, it indicates a fault in the lightning protection module, and it should be repaired or replaced promptly.
6. Suitable for indoor operation; if installed outdoors, a waterproof housing must be added.
All connections must be secure and reliable electrical connections.
8. Lightning protection grounding should comply with lightning protection regulations, with grounding wires as thick and short as possible, and the grounding resistance should be less than 10Ω.
