Easy peasy. Plug the Ethernet cables into each end (marked "Line" and "Equip") and attach the ground terminal to something grounded. (I used a 12AWG solid wire and a ground screw on my uninterruptible power supply.) Running Ookla Speedtest verified no degradation of signal. Hopefully, I'll never find out if it works. Review: Well made and grounded, but not shielded - This surge protector is clearly well-made (and others have mentioned that it saved their equipment). The metal RJ45 jack frames are connected to each other and to the ground connection, so it is compatible with shielded cable in the sense that it will conduct the shield connection. However, the device itself is not shielded (I took it apart to inspect how it was constructed). The case is plastic, so the device is a potential source of EMI entry. If you're looking for a shielded version that is completely encased in metal connected to ground, see Tupavco's TP302 (https://amzn.to/3IRJsaq) and my review about it. ## Features - DIN Rail Ethernet Surge Protector - Gigabit GbE PoE/High PoE+ (HPoE) 1000 Mbps LAN Ethernet Network - Gas Discharge Tubes for Full Protection GDT - Lightning Suppressor RJ45 Cable Protection CAT6/CAT5 - Standalone or DIN Mount Line-Line Line-Ground Protection,Bidirectional Clamping,5KA 8/20μs - Thunder Arrestor Protects Computer Networking Equipment Devices like Router,Modem,Camera,Switch etc ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078NKGPJC | | Best Sellers Rank | #77,118 in Electronics ( See Top 100 in Electronics ) #597 in Surge Protectors | | Brand | Tupavco | | Color | Black 67 | | Compatible Devices | Router, Modem | | Connectivity Protocol | Ethernet | | Connectivity Technology | Ethernet | | Control Method | Touch | | Controller Type | Switch | | Coverage | Power surges, lightning strikes, voltage spikes | | Customer Reviews | 4.1 out of 5 stars 88 Reviews | | Data Transfer Rate | 1000 gigabits_per_second | | Frequency | 5 GHz | | Frequency Band Class | Dual-Band | | LAN Port Bandwidth | 10/100/1000 megabits_per_second | | Manufacturer | Tupavco | | Maximum Upstream Data Transfer Rate | 1000 megabits_per_second | | Mfr Part Number | TP309 | | Model Name | TP309 | | Model Number | TP309 | | Number of Ports | 4 | | Other Special Features of the Product | DIN Mount, POE+ Gigabit | | Router Network Type | Wired | | Special Feature | DIN Mount, POE+ Gigabit | | UPC | 638362929471 | | Unit Count | 1 Count | | Wireless Communication Standard | 802.11ac | | Wireless Compability | 802.11ac | ## Product Details - **Brand:** Tupavco - **Color:** Black 67 - **Compatible Devices:** Router, Modem - **Connectivity Technology:** Ethernet - **Control Method:** Touch - **Frequency Band Class:** Dual-Band - **Model Name:** TP309 - **Number of Ports:** 4 - **Special Feature:** DIN Mount, POE+ Gigabit - **Wireless Communication Standard:** 802.11ac ## Images ![DIN Rail Ethernet Surge Protector - Tupavco TP309 - Image 1](https://m.media-amazon.com/images/I/71XeIc7FQvL.jpg) ![DIN Rail Ethernet Surge Protector - Tupavco TP309 - Image 2](https://m.media-amazon.com/images/I/610RF7beQdL.jpg) ![DIN Rail Ethernet Surge Protector - Tupavco TP309 - Image 3](https://m.media-amazon.com/images/I/61g58PM3b4L.jpg) ![DIN Rail Ethernet Surge Protector - Tupavco TP309 - Image 4](https://m.media-amazon.com/images/I/41N2NS1IqiL.jpg) ![DIN Rail Ethernet Surge Protector - Tupavco TP309 - Image 5](https://m.media-amazon.com/images/I/716T06fgV5L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this protect poe++ or just poe+?** A: From the manufacturer's website Nominal PoE Voltage <60 V Maximum continuous current 1.2 A Therefore you should be able to get 60 watts continuous, or Type 3 PoE++ **Q: What is a "gas discharge tube", and what is its function in this device?** A: A gas discharge tube is basically a over voltage protector. It is an open circuit until impinging high voltage enters an ionizes the gas inside which creates a low impedance presumably to ground. Only useful in a lightning incident (nearby or direct hit). If the latter then you are fundamentally screwed. I have photos to probe it. Message: if lightning is near (or predicted) then simply disconnect everything. Let us ALL float. I’m talking antennas, AC power cord and ground wires **Q: Does this device support 24v passive poe?** A: YES , this will easily support 24volt passive or non-passive POE. Normally POE is 48volts on power injectors or network switches. I know that it will support over 60 volts, as to smart 3 lens outdoor cameras that i have installed at Banks. This is , if you ground the DIN rail correctly to allow gas discharge tube to function properly to protect equipment. Gas discharge tube opens and closes data circuit, with no ground it will just act as a fuse and burn up after lightning strike. I always use TWO ethernet surge protectors , one on network switch rack and one upon entry into building with both TWO DIN rails grounded. Daniels Data Inc. - Dallas,TX - John Daniels **Q: How long of a rail do you need? What is the shortest length that I can use?** A: It mounts perpendicular to the dinrail so about 1” is minimum. I’d use enough too have two acres in the rail though or it will rotate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ No interference with signal *by D***N on May 30, 2022* I installed this surge protector between my cable modem and my router today.
