RECOMMENDED POSITION

Fig.7 - Recommended installation layout of Aurora inverters

NOTE

: Although the unit can also be installed in a slanted position (see fig.

8), pay utmost attention since in this case performance could be reduced
(Derating), due to worse heat sinking.

WARNING

: Unit surface may become very hot to the touch during

operation. DO NOT touch unit surface to avoid severe burns.
