Coarse protection

The modules incorporate overvoltage protectors. Additional protection can be provided by com-
mercially available connection boxes with gas-type surge arresters or the MDFU of the Hicom
125/130. National regulations must be observed. Generally speaking, the systems are not suit-
able for a cable that exits the building.
