Installation, Usage And Maintenance
1 This product can only be installed and maintained by qualified professionals. The installation position cannot be touched by hands. Ensure that it is uncharged and check whether the SPD is all right before installation. If there’s damage or the display window is red, the SPD can not be used any more; if the window is green, the SPD is normal.
2 The SPD should be installed behind the fuse (FU1) of the power supply circuit, with the capacity of the fuse not exceeding 125A gL/gG; otherwise another fuse (FU2) lower than 125A gL/gG should be provided in the surge protection branch circuit.
3 Refer to Fig. 3 for connection according to the marks on the SPD. The sectional-area of connecting line must be larger than 16mm2, as short as possible.
4 Connection of remote signalling alarm: the SPD is provided with remote signalling alarm interfaces (1 and 2 normally closed; 2 and 3 abnormally open), applicable for remote centralized monitoring or alarm.
Usage and Maintenance
1 After failure, the SPD shall be automatically disconnected with the power supply circuit through the internal thermal fuse system, the display window is changed from “Green” to “Red”, and remote signalling interfaces 1 and 2 are closed and 2 and 3 open. When the degradation indicating window is “Red” or there’s a remote alarm signal, the SPD should be changed immediately.
2 The display window of the SPD must be checked after the lightning storm
