2.4.2 Inverter placement
Clearances around the inverter
Always observe the specified minimum clearances to ensure good heat dissipation and adequate ac-
cessibility of the frequency inverter for servicing.
Inverter mounting orientation
Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.
Above the inverter
Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed
above the inverter should be heat resistant.

When using the inverters at the ambient
temperature of 40 °C or less, the inverters can
be installed without any clearance between
them (0 cm clearance).
When ambient temperature exceeds 40 °C,
clearances between the inverters should be
1 cm or more (5 cm or more for the FR-E740-
120SC or more).
