3.2 Treatment for inverter after longtime store
If the inverter store time is over one year, you must precharge the aluminium capacitor in the inverter again and install
the inverter after the aluminium capacitor characteristic recovering. For the specific method, please follow the grads in
belowing chart and give corresponding proportional voltage for every grad more than 30 mins while the inverter is
no-load.
If the input voltage of one grad is at the action critical point of contactor, fan or other equipments, please increase or
reduce the corresponding input voltage for the grad to avoid any component working under critical state.
