4.4. Connection Drawing
The following figure shows the connections between the drive, the
dynamic braking unit and the braking resistor.
Figure 4.5 Connections between drive – DB Unit (G1) – braking resistor.
Connection of the braking resistor trip
Notes:
•
Terminals B1 and P are the same one in the dynamic braking
units of the Group 2. Therefore, this terminal will be connected
to terminal B1 of the braking resistor and to the positive
terminal of the DC Bus of the drive at the same time. See
connections in figure 4.8.
