Potential separation and electrical safety for the temperature measurement input
• The temperature measurement input is double-insulated from the current and voltage
measurement inputs, as well as the supply voltage.
• There is no insulation from the RS232 and RS485 interfaces.
• There is only a functional insulation from the Ethernet and Profibus interfaces, and the
digital inputs / outputs.
• The external temperature sensor must be double insulated from the system parts that
carry voltages that are dangerous to touch (per IEC61010-1:2010).
