If you mean 'power up' your drone, don't worry, the self test will try to chirp the motors, this will turn the propellers a little bit, but usually causes no harm if they are prevented from spinning. Hopefully your drone will prevent you from arming the motors, or trying to take off without your propeller arms in place properly, but if not, please be careful to make sure things are unfolded before arming the drone, serious damage can occur to the motors if they are restricted, and to the drone if it flips around.
