Recommended clearances for the facilitation of service work
In order to facilitate service work, minimum clearances to the rear and sides of 1,000 mm are recommended. If you
are using a service tent during installation and service work, maintain 5,000 mm clearance to the inverter.
12.1.1.2 Minimum Clearances in Electrical Equipment Rooms
Damage due to intake of exhaust air or blocked exhaust air outlets
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 exhaust air vents are not obstructed.
• Make sure that the exhaust air vents are accessible for cleaning at all times.
• Ensure that the minimum clearances are complied with.
