High altitude
Use the inverter at an altitude of within 2500 m. For use at an altitude above 1000 m, consider a 3% reduction in the rated
current per 500 m increase in altitude.
If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric
strength.
Vibration, impact
The vibration resistance of the inverter is up to 5.9 m/s

(2.9 m/s

or less for the FR-F860-02890 or higher) at 10 to 55 Hz
frequency and 1 mm amplitude for the directions of X, Y, Z axes. Applying vibration and impacts for a long time may loosen the
structures and cause poor contacts of connectors, even if those vibration and impacts are within the specified values.
Especially when impacts are applied repeatedly, caution must be taken because such impacts may break the installation feet.
Countermeasure
• Provide the enclosure with rubber vibration isolators.
• Strengthen the structure to prevent the enclosure from resonance.
• Install the enclosure away from the sources of the vibration.
2.3.2 Amount of heat generated by the inverter
Regarding the amount of heat generated in the FR-F860 series inverter
The amount of heat generated by the FR-F860 series inverter is shown in the following tables.
• The amount of heat generated shown assumes that the output current is inverter rated current, power supply voltage is
575 V, and carrier frequency is 2 kHz.
