 Vibration, impact
The vibration resistance of the inverter is up to 2.9 m/s
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.
