Fig. 18 shows the 8230 frequency inverter power connections for a 3AC supply. The
8230 frequency inverter supply components marked * are not essential.
Note:
In exceptional cases it can be necessary to reverse the order of components 1), see
Fig. 18. This is the case, for example, if additional auxiliary supplies such as external
motor fans are to be operated at the feed point or function earthing is not consistent.
