 Installation and wiring
1)  According to protection demands, the SPD is connected by series between protected devices and signal path,
the closer the distance to protected devices, the better the protection effect.
2)  To connect separately a)the cable to the input terminal of power, video and control port, b) output terminal
of SPD power, video and control to related interface of protected devices, c) ground line of SPD to earth wire
of lightning protection system
3)   After wiring, please check it until everything is going well, to put into operation.
 
Product maintenance
1)   The product does not need to be maintained specially, but to inspect at fixed period, especially before and
during thunderstorm season.
2)   Once there is a failure during system operation, please remove the SPD device at first, if the system can
operate normally, the device is broken
