6.1 Non-repairable Units
H1-H5 and I2-I4 are non-repairable units and should not be
repaired. The information about Line/Motor/UDC+-
terminals is useful to verify what went wrong with these
frequency converters, for statistics and WIIS purposes, but
also to avoid replacing a frequency converter that is
actually not defective.
