Precharging the AFE
This section contains important information about AFE precharging.
Introduction
An AFE in the IP20 2500 MCC Style enclosure contains an internal
precharging circuit. The precharging unit is used to charge the DC bus
capacitors. The charging time depends on the capacitance of the intermediate
circuit and the resistance of the charging resistors.
shows the technical
specifications for the precharge in the AFE enclosure. For correct operation of
the precharging circuit, verify that the input circuit breaker (Q0) is on, and the
input contactor (K1) and precharging circuit contactor are controlled by the
AFE.
