12 Introduction to the manual
WARNING! Make sure the energy storage is disconnected from the DC/DC
converter and from the drive DC bus before doing any work on the DC/DC
converter module or on any other device connected to the common DC bus.
When the energy storage is connected to the DC/DC converter, the energy storage is also
electrically connected to the common DC bus via the freewheeling diodes inside the
DC/DC converter.
WARNING! If an energy storage is used for charging a common DC bus from
zero, there must be a pre-charging circuit to do this. Otherwise the energy storage
is immediately connected to the DC bus via the freewheeling diodes inside the
DC/DC converter module, and the direct charging along with the resulting high current can
damage the DC bus capacitors.
