heat produced inside the enclosure can be
reduced and likewise the size of the enclosure
can also be reduced. Mounting the inverter in
an enclosure with the heat sink p
outside requires an optional dedicated special
metal fitting. To mount the inverter in an
enclosure with the heat sink positioned
outside, cut out the enclosure panel according
