NOTES
For replacing the cooling fan of the 04320 or more, 30cm of space is necessary in front of
the inverter. Refer to section 8.1.7 for fan replacement.
Since the fan cover of the inverter FR-F746 is fixed with screws, leave enough clearances
so that the screws can be removed with a driver and such.
It is not necessary to leave spaces on both sides of the inverter FR-F746.
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.
NOTE
The ambient temperature should be 50°C or less for the inverter FR-F740 and 40°C or less
for the inverter FR-F746 at a distance of 5cm from the centre bottom of the inverter.
