Maintenance and Inspection
Monthly and Yearly Inspection Chart
Note 1:
The life of a capacitor is affected by the ambient temperature. See “Capacitor
Life Curve” on page 6–11.
Note 2:
The inverter must be cleaned periodically. If dust accumulates on the fan and
heat sink, it can cause overheating of the inverter
