Shown below the notes about installation clearance of a unit.
1
Installation clearance at above and below the unit.
Please have clearance of at least 25mm above and below the
unit to avoid heat accumulation.
2
Installation clearance at the side of the unit.
Please have clearance of at least 15mm side the unit to avoid
interfering with heat radiation from housing. However, refer to
Table 4.1, if adjacent device of the unit (including power supply) is
a heat source.
