Installation Instructions:
1. Power must be cut off before installation, and live operation is
strictly prohibited
2. It is suggested to connect the fuse or automatic short-circuit
in series at the front end of the lightning protection module
3. Please connect according to the installation diagram, where + is
the positive wire, - is the negative wire, and PE is the ground
wire. Don't make a mistake. After the installation is completed,
close the switch and check whether the working condition is normal
4. Insert the module in place after installation and check whether
the lightning protection module works normally
5. During the use of SPD, it should be regularly monitored and
checked the status of the fault display window. When the fault
display window is red or the remote terminal output an alarm
signal, it indicates that the lightning protection module has
broken down and should be repaired or replaced in time
6. Lightning protection module should be installed in parallel, and
the connecting line should be firm and reliable, and it should be
short, thick and straight
Combine usage:
1. 4P surge protector is installed in the three phases of the TN-S
system
2. 3P surge protector is installed in the three phases of TN-C or
IT systems
3. 2P surge protector is installed in the single phase of the TN
system
4. 1P surge protector can be freely combined and installed in
various occasions
5. 3+1 and 1+1 surge protectors are used in TT distribution systems
The classification of the SPD:
1. According to the working principle divided:voltage switching
type SPD, voltage limiting type SPD , voltage cobination type SPD
2. According to the use of points : power system surge protection
device, signal system surge protection device
