Application:
It is suitable for the second level lightning protection of single-phase power system
Generally used in 1-2 boundary lightning protection area
Installation and Maintenance:
After installation, check whether the protection unit is inserted in place, close the circuit breaker (fuse) switch, and check whether the working state is normal.
When the fault indication window changes from green to red, please replace it as soon as possible.
