RECONDITIONING THE BUS CAPACITORS
If this drive has been in storage for over one year it
is necessary to recondition the power supply bus
capacitors. To recondition the bus capacitors, apply
the AC Line, with the drive in the Stop Mode, for a
minimum of one hour. Not following this procedure
will cause the bus capacitors to fail.
