Overvoltage category | III | Insulation type | Double isolation (basic isolation and supplementary isolation by impedance/current measurement transformer) Safe isolation from the adjacent SELV/PELV modules must be ensured. The product manual contains the types of isolation to adjacent modules in section “Isolation to Adjacent I/O Modules per EN/UL 61010 2-201.” Without double or reinforced isolation, the 750-495/000-00x Power Measurement Module must not be placed directly next to SELV/PELV modules. Under such conditions, the 750-616 Distance Module must be used. |
