Notices
●Choose the appropriate protection mode (3+1, 4+0, 1+1, 2+0) according to the power system type.
●Select matching circuit breakers or SCB releases to ensure coordination with the power system.
●Use wiring with cross-sectional area 6mm²-25mm² and tighten screws to 5N·m torque.
●Ensure reliable grounding with ground resistance ≤4Ω to guarantee protection effect.
●Regularly check the lightning counter and status indicator—reset the counter or replace modules as needed.
●Install the box in a dry, well-ventilated indoor environment; avoid exposure to moisture or direct sunlight.
