Placing of the commutation choke
If the frequency converter is connected to an external commutation choke, the
connection of the power feedback unit has to be done at it's network terminals
(figure 2.6.3). Is the connection done at the load terminals of the commutation
choke it's inductivity prevents the synchronising to the supplying net and the
induction voltage of the choke when it is switched of under load may result in
damages to the power feedback device.
STOP!
Over voltages may cause serious damages to the connected frequency in-
verter and /or to the power feedback unit and to the other loads.

Not allowed!
The same things apply to the also non-admissible pre-connection of further
commutation chokes.
