Important hint:
The example shows the principle structure of
a DC drive and its connections. It is a not
binding recommendation, and it cannot re-
spect all conditions of a plant. Therefore
each drive must be considered separately
and with respect to the special application.
Additionally the general installation and safety
rules must be taken in account.
