For the application prototypes of the supply units, the "WARN" con‐
tact had been realized as N/O contact. As of the following hardware
indices (HWIs), the "WARN" contact is realized as N/C contact:
● HMV01.1E-W0030: as of HWI -14
● HMV01.1E-W0075: as of HWI -14
● HMV01.1E-W0120: as of HWI -15
● HMV01.1R-W0018: as of HWI -17
● HMV01.1R-W0045: as of HWI -17
● HMV01.1R-W0065: as of HWI -18
