Vibration, impact The vibration resistance of the inverter is up to 5.9 m/s 2 (2.9 m/s 2 or less for the FR-A840-04320(160K) 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. 40 2. INSTALLATION AND WIRING 2.3 Installation of the inverter and enclosure design
