7 Installing the H-AST
Additionally required equipment
☐ Isopropyl alcohol
Procedure:
1. Check whether printed circuit board retaining clips
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 is not damaged or contaminated.
4. On the rear side of the H-AST, check the pattern of
thermally conductive plastic for damage and
impurities.
