Installation Method and Precautions:
- The power connecting wire use multi-strand copper wire and not less than 6mm2, ground wire use multi-strand copper wire and not less than 10mm2. Connecting wire should be short, straight, thick. Ground Resistance: R 4
- The front-end of DC high voltage surge protection SPD should be with appropriate fuse in series or be disconnected. Must disconnect power when install, prohibited hot-line operation.
- Insert Lightning protection module in place correctly after finished installation, check if working normally.
- When the DC high voltage surge protection SPD module fault display window indication red (remote communication terminal output an alarm signal), then means the SPD happen fault and should be replaced.
- DC high voltage surge protection SPD not need special maintenance, just need regularly check if connections is loose, status indication is normal.

FAQs of DC High Voltage Surge Protection SPD:
Q: How does the DC High Voltage Surge Protection SPD function in solar PV systems?
A: The SPD detects and diverts transient surge voltages in DC power lines, commonly caused by lightning or switching events, thereby protecting sensitive equipment in solar photovoltaic systems from damage.Q: What is the installation process for this surge protection device?
A: Install the SPD directly onto a 35 mm DIN rail. Use the screw terminals to secure wiring, and ensure correct connection according to the SPDs rated voltage. Monitor the mechanical indicator window for any status changes.Q: Where should this SPD be placed for optimum performance?
A: The SPD should be installed as close as possible to the equipment or main DC distribution panel to offer immediate protection. Placement near entry points of DC power, such as inverter inputs and combiner boxes in solar PV systems, ensures optimum efficiency.Q: What are the benefits of using a mechanical indicator window on this SPD?
A: The mechanical indicator window provides a quick and clear visual status (green for normal, red for fault), allowing for fast maintenance responses and minimizing system downtime.Q: When is it necessary to replace the surge protection device?
A: Replacement is required when the indicator window switches to red, signaling the SPD has reached its end of lifespan or has operated during a major surge event, to maintain continuous protection.Q: What applications are suitable for this SPD model?
A: It is ideal for DC power systems, solar PV setups, and industrial DC circuits, particularly in environments with voltage ratings of up to 1500V DC and subject to harsh temperature variations.Tell us about your requirement
