12.1.1.2 Minimum Clearances in Electrical Equipment Rooms

Damage due to intake of exhaust air or blocked ventilation openings
The supply air is intended to cool the inverter components. Failure to observe the specified minimum clearances can
result in warm exhaust air from the inverter being drawn in. This increases the risk of a thermal short circuit. Property
damage due to yield loss and damage to the components may result.
• Ensure that no exhaust air can be drawn in through the air inlets.
• Ensure that it is not possible for exhaust air to be drawn into the air intake of other devices.
• Make sure that the air inlets are not obstructed.
• Make sure that the exhaust air vents are not obstructed.
• Make sure that the ventilation openings are accessible for cleaning at all times.
• Ensure that the minimum clearances are complied with.
