Line/Load Connection - Siemens SINAMICS S120 Manual

Same phase sequence in the precharging and main circuits
It is absolutely imperative that the precharging and main circuits have the same phase
sequence. If this is not the case, during the brief overlap period, where both contactors are
simultaneously closed, the precharging resistors will be overloaded and could be
destroyed.
