Notices
1.Confirm the POE voltage matches 48Vdc when using SX-10G/POE to avoid device damage.
2.Use shielded Cat-6 or Cat-6A cables to enhance anti-interference performance and signal stability.
3.Ensure proper grounding to guarantee surge diversion efficiency; ground resistance ≤4Ω is recommended.
4.Install the SPD in the front-end of network devices (routers, switches, cameras) for optimal protection.
5.Avoid overloading the load current (1A) to prevent overheating or signal disruption.
6.Failure is indicated by signal interruption; inspect the product if network connectivity is lost unexpectedly.
