are in place at the appropriate positions in the
inverter. If any printed circuit board retaining clips
are missing, insert the supplied printed circuit board
retaining clips in these positions in the enclosure.
2. Clean the supporting surfaces in the enclosure. To
do so, use isopropyl alcohol and a lint-free cloth.
3. Carefully remove the H-AST upwards out of the packaging. When doing so, ensure that the

thermally conductive plastic for damage and
impurities.
