Installation of the replacement DC link is performed in the reverse order
of its removal.
The installer must ensure that the flexible DC link leads are connected to
the appropriate terminal and routed so that electrical clearances are
maintained. You must also verify that the nameplate ratings are the same
or appropriate for the drive system. A different DC link will require
different parameter settings.
Thermal protection of the DC link reactor is provided by two normally
closed contacts wired to the I/O module. These contacts will open at
190°C and cause a fault/alarm message to be displayed.
