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 not
defective.
