Precautions: |
1. The product is connected in series. When installing, the lightning protection device is connected between the external line and the protected equipment according to the corresponding interface.
2. The components in the lightning protection device are strictly inspected, and no special maintenance is required during normal operation. Take it off, measure the resistance between the input and output of the network signal should be ≤ 5Ω, the input and output of the power supply should be ≤ 1Ω, and the resistance between each core to ground should be ≥ 10ΜΩ. If the measured data does not meet the above requirements, indicating that the product is faulty, it should be replaced in time;
3. The lightning protection device should be well grounded, the lightning protection ground wire should be as short, thick and straight as possible, and the grounding resistance should comply with relevant national standards.
