Abstract
A plurality of inductive loads () are connectable in parallel with one another between first and second terminals (), to which a controllable voltage () is applied. A method () for operating the loads () includes the steps of detecting () the connection of a previously non-energized load () between the terminals (); setting () the voltage () to a predetermined first value (), and, after the lapse of a predetermined time interval (), adjusting the voltage () to a predetermined second value (), with the second value () being lower than the first value ().
