Reserve the right for technology revise
1. the installation of the SPD
Standard 35mm mount rail, install in the general power distribution cabinet.
2. the connection of the SPD
2.1 Single phase SPD connection way shows as figure 1, figure 2, three phase SPD connection way shows as figure 3, and detailed connection please check attached instruction.
2.2 There is an alarm terminal on the SPD. Connection port is on the lower part of the base plate. If long distance control needed, connect the alert device in open circuit.
2.3 When the connection finished, please check it whether it is correct and credible, after that, switch on the power, if the LED shows green color, then the alarm system is on working and the connection is correct.
