Connection at 400 V mains
AC or three-phase voltage supply
autotransformer or isolation transformer
one transformer for several devices
Notice:
-set safety contacts on transformer inrush current.
-slow fuses in front of the transformer
-fuse value corresponding to the transformer rated current
-quick fuses after the transformer
-fuse value for each power supply unit max. 30AF
