Installation Tips

1.Install the lightning protection box in a dry, well-ventilated indoor environment, and keep it away from flammable materials.

2.Use wires with a cross-sectional area of 2.5mm²~10mm², and tighten the screws to a torque of 5N·m.

3.Ensure reliable earthing, with a ground resistance ≤4Ω, to achieve optimal surge discharge effect.

4.Regularly check the lightning count and status indicator: if the product fails, the indicator will turn off. Replace the faulty device in a timely manner.

5.Do not connect the product to a power supply that exceeds its rated voltage and current.

6.Avoid using the product beyond the specified temperature and humidity ranges.


FAQ
Q1: What is the counting range of the lightning strike counter?
A1: The counter can record lightning strikes with a discharge current ranging from 3kA(8/20μs) to 80kA(8/20μs), with a digital display range of 0 to 999.
Q2: Does the product support remote monitoring?
A2: Yes. It is equipped with normally closed and normally open remote signaling contacts, allowing connection to a monitoring system for remote status tracking.
Q3: What is the difference between LPX-40C and LPX-80C?
A3: The core difference lies in the maximum discharge current (Imax): LPX-40C has an Imax of 40kA, while LPX-80C has an Imax of 80kA, making them suitable for different system protection requirements.
Q4: Can it be installed in outdoor environments?
A4: No. This product is designed for indoor use only. For outdoor applications, please select products with an IP67 protection level.
