Potential isolation and electrical safety of the residual current measurement inputs
·The RCM measurement inputs are double insulated relative to the current and voltage measurement
inputs as well as to the supply voltage.
·There is no insulation to the temperature measurement input.
·There is only functional isolation relative to the Ethernet, Profibus, RS-485 and digital I/O interfaces.
·The connected residual current transformers and the lines to be measured must each have at least an
additional or a basic insulation in accordance with IEC61010-1:2010 for the mains voltage applied.
