The heat generated by the Sunny Central (exhaust air) must be dissipated to comply with the
maximum permitted ambient temperature. We recommend routing the exhaust air (air duct) out of the
electrical service room.
Overview of the Air Inlets and Outlets
The positions of the air outlets differ depending on the Sunny Central model selected. During
installation, ensure that the air inlets and outlets are not covered.
If routing the exhaust air through the rear wall of the Sunny Central, the exhaust air can be routed
directly out of the building via a weatherproof grille installed on-site in the building wall. The Sunny
Central can then be set up with the rear of the cabinet directly against the opening in the building
wall. Remove the finger guard from the fan openings and secure a seal or frame-like air hood to the
building wall.
Air Routing for the "EVR" Option
If the "EVR" option was selected, the exhaust air cannot be routed through the top of the
Sunny Central.
NOTICE!
Overheating impairs the operation of the Sunny Central.
Ensure that the Sunny Central is sufficiently cooled:
• Provide the required air volume for the Sunny Central.
• Clean the ventilation openings (filter pads) and the exhaust air bars at regular
intervals. See the Sunny Central maintenance manual for the exact cleaning intervals.
• Route the exhaust air separately from the individual cabinet units (air outlets of the
power units and the switch cabinet) to prevent thermal short circuits.
DANGER!
Loss of limbs!
If the exhaust air is routed directly out of the building, the rotor blades of the fan are not
protected against contact.
• When cleaning the ventilation duct, switch off the Sunny Central.
• Do not start to clean the ventilation duct until the rotor blades of the fan have come
to a stop.
