*1. The life of the capacitor depends on ambient temperatures. Refer to the product life curve in Appendix-2.
When the capacitor stops operating at the end of the product's life, the Inverter must be replaced.
*2. Clean the Inverter periodically. Accumulated dust in or on the cooling fan or heat sink can cause the Inverter
to overheat.
