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 relative to the RCM measurement input.
·There is only functional isolation relative to the Ethernet, Profibus, RS-485 and digital I/O interfaces.
·The external temperature sensor must be double insulated relative to system components with dan-
gerous contact voltage (according to IEC61010-1:2010).
