Function
The PRD-DC direct current surge arrester is designed to protect photovoltaic panels
and the "DC" input to the inverter from overvoltages due to a lightning strike.
It should be installed in a switchboard inside the building. If the switchboard is located
outside, it must be weatherproof.
Withdrawable PRD-DC surge arresters allow damaged cartridges to be replaced
quickly. They offer remote reporting of the "cartridge must be changed" message.
