Potential isolation and electrical safety of the temperature measurement inputs
·The temperature measurement input is double insulated relative to the current and voltage measure-
ment inputs as well as to the supply voltage.
·There is no insulation to the RCM measurement input.
·There is only a functional insulation relative to the Ethernet, Profibus, RS-485 and digital I/O interfac-
es.
·The external temperature sensor must be double insulated relative to hazardous contact voltage (ac-
cording to IEC61010-1:2010).
