Test voltage | 3.51 kVAC, 50/60 Hz, 1 min. | Rated surge voltage | System/field side: 5.0 kV (EN 60870-2-1 / Class VW3) 6.4 kV (EN/UL 61010-1) |
System voltage | ≤ 600 V | Note on system voltage | To ensure safe insulation, the module's N connector must not be connected. The system voltage corresponds to the line conductor/neutral conductor voltage, which was derived from standard power supply systems |
Overvoltage category | III up to 3000°m; II at 3000°m … 5000°m | 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 750-495/040-00x Power Measurement Module must not be placed directly next to SELV/PELV modules. Under such conditions, the 750-616/040-000 Distance Module must be used. |
