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
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.
A2: Yes. It is equipped with normally closed and normally open remote signaling contacts, allowing connection to a monitoring system for remote status tracking.
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.
A4: No. This product is designed for indoor use only. For outdoor applications, please select products with an IP67 protection level.
