1000M Surge Protector SPD DPR Gigabit Ethernet

Temperature: -40℃~+80℃; Relative humidity: not more than 95% (25℃); Atmospheric pressure: 'not less than 74.8kpa
3. How it works
The lightning arrester is connected in series with the input end of the protected equipment. When the transmission line is induced by lightning to generate overvoltage, the lightning current is quickly released to the ground through the lightning branch of the lightning protection device, and the output voltage box of the lightning protection device is located in the equipment. within the withstand voltage range. So as to ensure the safe operation of the equipment.
5. Use and maintenance
5.1 Installation Instructions
5.1.1 Before the lightning arrester is connected to the system, first check the grounding resistance of the grounding grid, whether it meets the requirements of the specification, and should be ≤4Ω.
5.1.2 The lightning arrester is connected to the front end of the protected equipment, and the interface connection must be reliable.
5.1.3 Connect the grounding wire of the lightning arrester to the protective grounding busbar of the equipment room. The grounding wire should be as short and straight as possible, and the grounding length should not exceed 500mm.
5.2 Notes
5.2.1 There are input (IN) and output (OUT) marks on the surge arrester. The output terminal should be connected with the protected equipment, do not connect it in reverse. Otherwise, the lightning arrester will be damaged when lightning strikes, and the equipment will not be effectively protected.
5.2.2 Users are not allowed to disassemble the fasteners of various parts of the lightning arrester at will, so as to avoid damage, affect normal work, or even affect signal transmission or signal interruption
5.3 Inspection of the surge arrester 5.3.1 Use the three-meter "Ω×1" to measure the resistance between the input core wire and the output core wire of the surge arrester, which should be approximately zero; minecraft.
5.3.2 Use the three-meter "Ω×10k" gear to measure the resistance of the core wire to the mine ground and the shell to the mine ground, which should be infinite. If the measured resistance does not match the above, the lightning arrester should be replaced.
