	the appendix.

Air cooling	Door/roof openings
	Explanation of "arcing short-circuit":
	An underpressure is created in the openings of the cabinet doors due to
	the flow of air. This is dependent on the volumetric flow and the
	hydraulic cross-section of the openings.
	The flow causes a build-up (over) pressure in the roof or in the top
	cover.
	As a result of the difference in pressure between the overpressure at
	the top and the underpressure at the bottom of the cabinet, a flow of air
	is created inside the unit, a so-called arcing short-circuit. This can be
	stronger or weaker depending on the volumetric flow and the door/roof
	opening cross-section.
	Due to the air flow inside the AFE inverter, preheated air starts to enter
	the heatsink which causes the equipment to overheat. In addition, a
	different, more unfavorable operating point is set for the fan.
