The power controllers switch on chronologically staggered. Starting from the
dashed lines, the dispersion of power takes place symmetrically to the left and
right (see arrows). For as long as the total output level of the two devices is be-
low 100 %, overlaps of the two device currents in a single phase are prevent-
ed. The next power level in the network is not started until the total output level
exceeds 100 %.
A
If a power controller performs a restart when the configuration level
is exited, it no longer operates synchronously with the others.
All master-slave devices have to be switched on again simultane-
ously via a joint main switch!
