Installation reminder
1.Install the SPD in LPZ 0A-B or subsequent lightning protection zones to ensure effective T1+T2 protection.
2.Use wiring with cross-sectional area 2.5mm²-32mm² and tighten screws to 5N·m torque.
3.Ensure the grounding system meets requirements (ground resistance ≤4Ω) for optimal surge diversion.
4.Replace the product immediately if the visual window turns red (failure status).
5.The product supports transient overvoltage (TOV) resistance up to 442V for 120 minutes, suitable for unstable power grids.
6.Avoid using the product beyond the specified temperature (-40℃~+80℃) and humidity range.
