     Terminal Designations  (Excerpts from DIN Standard 72 552)
     The terminal designations do not identify the conductors, because device
     with different terminal designations can be connected at the two ends of
     each conductor.  If the number of terminal designations is not
     sufficient (multiple-contact connections), the terminals are
     consecutively numbered using numbers or letters whose representations
     of specific functions are not standardized.
