WARNING.
The DC BUS discharge period may extend for up to 10 min
after the equipment has been disconnected from the electrical mains. For
this reason, always ensure that there is no voltage in the DC BUS before
handling the equipment.
WARNING.
The auxiliary power supplies carry out the task of supplying the
electrical control circuits and signals to manage the other modules
connected to the DC BUS.
Never use these power supplies to power the
brake of a motor.
The brake may generate voltage peaks that could
damage the unit.
