Potential isolation and electrical safety of the digital inputs and outputs
·The digital inputs and outputs are double insulated relative to the current and voltage measurement
inputs as well as to the supply voltage.
·There is only functional isolation relative to each other and to the Ethernet, Profibus, RS-485 and
digital I/O interfaces.
·The auxiliary voltage to be connected externally must be realized as SELV or PELV.
