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).
