Connection example for applications to 630 A
The motor current is calculated with the current measuring module 3RB29.6‑2.... The evaluation
module is connected to the current measuring module by a ribbon cable (3RB2987‑2.).
Note
Connection of the main circuit is shown in the operating instructions of the current measuring
module. You can find more information in Chapter "References (Page 126)"
