5. Installation Method and Precautions:
(1) The power connecting wire use multi-strand copper wire and not less than 6mm2, ground wire use multi-strand copper wire and not less than 10mm2. Connecting wire should be short, straight, thick. Ground Resistance: R≤4Ω
(2) The front-end of SPD should be with appropriate fuse in series or be disconnected. (3) Must disconnect power when install, prohibited hot-line operation.
(4) Insert Lightning protection module in place correctly after finished installation, check if working normally.
(5) When the SPD module fault display window indication red (remote communication terminal output an alarm signal), then means the SPD happen fault and should be replaced.
(6) SPD not need special maintenance, just need regularly check if connections is loose, status indication is normal.
