Evaluation Kit EASYKIT AUX DRIVES (FS50R07W1E3_B11A)
2.2 Connect Supplies and Load
The Evaluation KIT has to be connected to a 8..18V auxiliary supply, which can deliver at least 2A. On the
HV power connectors a supply <450V and a 3ph induction machine (or equivalent load) has to be applied.
The connections are illustrated in Figure 5.
Please take note that only the aux supply is reverse polarity protected up to -20V. The power terminals for
the <450V DCL supply is not protected against reverse polarity events and will lead to failed diodes if current
is not limited.
