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 measure-
ment inputs as well as to the supply voltage.
• There is only functional isolation from each other and from the Ethernet, Profibus, RS-485 and
digital I/O interfaces.
• The auxiliary voltage to be connected externally must be realized with SELV or PELV.
