Description of products
POE Surge Protector Series is used for protection of the interface circuit of high speed Ethernet. It is connected in the input end of protected equipment. When the transmission line is struck by lightning, the lightning current is discharged to the earth by lightning branches, and the lightning overvoltage is clamped within a proper range, thus the security of equipment being ensured.
- Total Maximum discharge current(Imax) 20kA(8/20µs
- POE power supply part with thermal protection
- Low limit voltage
- Small insertion loss
- Data transmission rate up to 1000Mbps
- Small volume,easy installation
Installation and maintenance
1 Installation method
1.1 Firstly, put system signal lines connected to the surge protector's input terminal, and the output terminal connected to the protection devices end, not allowed to be anti-line, also need to ensure the RJ45 connector joint part have reliable touch.
1.2 Making the earthing conductor of surge protector connected to the nearest protecting earthing busbar or the equipment's metal shell.
2.1 First, checking the connection between surge protector's earth wire and ground network whether meet requirements.
2.2 Surge protector's enclosure marked IN and OUT, the connection between output terminal and the device to be protected is not allowed to be anti-line. Otherwise, it will damage surge protector, and can't protect the equipment effectively.
2.3 User can't dismantle the fastener of surge protector casually, so as not to affect the normal operation of the product.
2.4 After the surge protector connected to system, once found the system don't work normally. However, it can be worked normally after remove the surge protector,may have problem on choice of surge protector, need to replace it.
