230 V AC mains voltage

Working on the electrical installation is only allowed if the system is de-energised.
Components must be installed and commissioned only by qualified personnel. Local regulations must be complied with.

Ensure that the system is de-energised by switching fuses to off before working on a digitalSTROM installation.
Reason: Other than in conventional installations one has to note that in a digitalSTROM installation the digitalSTROM terminal blocks conduct mains voltage on the input side even if the consumers are switched off.
Switching off a consumer (e.g. lamp) with the push button does not de-energise the terminal block!
