Installation instruction
1. The protector connected in serial between the signal channel and the protected device in order to avoid lightning the antenna feeder lightning protection device should be connected in series at the output terminal of antenna and input terminal of protected device respectively
2 Connect the earthing wire of the protector to the equalizing ring of the lightning protection system the earthing wire length should be less than 0 5m
3. Free special maintenance when fault occurs in the system dismantle the protector and then if the system resume normal it is that the protector was broken and need to be replaced.
