Installation of the inverter and enclosure design
 Removal of the rear installation frame
Two installation frames are attached to each of the upper and lower
parts of the inverter. Remove the rear side installation frame on the top
and bottom of the inverter as shown on the right.
 Installation of the inverter in enclosure
Place the inverter in an enclosure so that the inverter's heat sink section protrudes from the hole through the panel of the
enclosure. Fasten the inverter to the panel with screws through holes in the upper and lower installation frames.

NOTE
• As the heat sink section protruded through the panel includes a cooling fan, this type of installation is not suitable for
environment in which the inverter may be exposed to drops of water, oil mist, dust, etc.
• Make sure that screws, debris etc. do not get into the inverter and cooling fan.

To avoid interference with small protrusions (finger guard
protective cooling fan covers) on top of the heat sink, the
thickness of the panel of the enclosure should not exceed
10 mm (marked with *1 in the figure below) and the space
around the covers (fans) should be cleared.
