Installation Method Of Signal Spd

The installation of signal SPD is different from that of AC and DC in that signal SPD is connected in series in the line to achieve high and low frequency, single and double pair line full mode protection mode.

1. Installation of control signal SPD

The control signal SPD is installed on the line in a connection mode with input at one end and output at the other end. Here, taking the 2-wire system as an example, there are five wiring ports (I1, I2, O1, O2, PE), I1 and I2 are input ends, O1 and O2 are output ends, and PE is grounded.

2. Installation of network signal SPD

Network signal undoubtedly refers to the protection of network cable lines. Network SPD is also connected in series in the network cable line. It has 3 wiring ports (RJ45 input end, RJ45 output end, PE). The network cable is inserted into both ends of the SPD through the RJ45 interface connection mode. The network cable is an 8-wire system, so it can be seen from the network SPD schematic diagram that there are 8 line input channels
