Notices
1.Install the SPD in LPZ 1-2 or subsequent lightning protection zones, ensuring the distance to protected equipment does not exceed 10 meters.
2.Use wiring with cross-sectional area 2.5mm²-10mm² and tighten screws to 5N·m torque for secure connections.
3.Ensure reliable grounding with a ground resistance ≤4Ω to guarantee surge current diversion efficiency.
4.Replace the SPD immediately if the LED indicator turns off (failed status) or after experiencing a severe surge impact.
5.Do not disassemble the product by yourself; improper operation may damage internal components and cause safety risks.
6.Avoid using the product in environments beyond the specified temperature (-40℃~+80℃) and humidity range
FAQ
Q1: What is the difference between SLV-40T and SLV-80T?
A1: The core difference is nominal discharge current (In) and maximum discharge current (Imax): SLV-40T has In=20kA/Imax=40kA, while SLV-80T has In=40kA/Imax=80kA. Other performance parameters and structural design are consistent.
Q2: Can this SPD be used for single-phase power systems?
A2: No, SLV-40T/SLV-80T is specifically designed for three-phase systems. For single-phase applications, choose SLV-40S/SLV-80S series products.
Q3: What is the function of remote signaling contacts?
A3: The normally closed and normally open switching contacts allow connection to monitoring systems, enabling remote alerts when the SPD fails.
Q4: Does the product require regular maintenance?
A4: Regular visual inspection is recommended (quarterly): check LED status and wiring tightness. No additional maintenance is needed under normal operating conditions.
Q5: Is the SPD compatible with different grounding systems?
A5: Yes, it is compatible with TN, TT, and IT grounding systems, as long as the grounding resistance meets the requirement (≤4Ω).
