Installation and wiring
a) HD-SDI camera SPD is connected by series between protected devices and signal path
b) The closer the distance between SPD and protected device, the better the effect
c) To connect ground line of SPD to lightning protection system ground device, lower connecting wire is better, within 1m
Product maintenance
1) The HD-SDI camera SPD 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 |
