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