3.2.4 Capacitor reforming Guide after long storage
For correct performance of this product after long storage before use it is important that Inverter Capacitors
are reformed according to the guide below:
• 1 to 2 years storage: Apply 100% rated voltage for one hour.
• 2 to 3 years storage: Apply 25%, 50 % , 75% and 100% at 30 minutes intervals.
