Installation Guide

In the following a schematic top view of the Sunny Boys located in a station is shown. The installation
of the inverters is realized as a "right-hand system" (above) and "left-hand system" (below).

4.1.5 Ventilation

For cooling the inverter, an appropriate air supply is necessary. To guarantee secure operation and
the maximum of feed-in power, the allowable ambient temperature has to be observed.
The required air is drawn through the switch cabinet doors and is blown out via the roof or the back
wall of the cabinet unit depending on the Sunny Central model Thus the devices can be installed
directly adjacent to each other. The air needed as well as the appropriate distance to the wall can be
found in the "Sunny Central Installation requirements" (separate document). Filters which clean the
absorbed air are installed at the air inlet openings.
Should the required amount of air at the installation site of the Sunny Central be too low, a larger
amount of air has to be made available (supply air bars, fan etc.) through construction measures.
The inlet air must satisfy the requirements of classification 3S2 (see table). The operation of the inverter

is suited to a relative humidity of 15 … 95 %.

WARNING!
Smoke in electrical areas of operation

We recommend the installation of a smoke detector inside the operating room which
controls the external emergency-stop connection of the device and which switches off the
Sunny Central in the event of smoke.
