Potential isolation and electrical safety of the interfaces
·The RS-485, Profibus and Ethernet interfaces are double insulated relative to the current and voltage
measurement inputs and the supply voltage.
·There is only a functional insulation from each other and from the RCM and temperature measure-
ment inputs as well as from the digital I/Os.
·The interfaces of the devices connected here must have double or reinforced insulation against mains
voltages (according to IEC 61010-1: 2010).
