5.2 Inspection and Replacement of the Damageable Part
 Filter Capacitor
Pulsating current of the main circuit will influence on the performance of the
aluminum electrolytic filter capacitor, the impact depends on the environment
temperature and working condition. In normal condition, the controller shall replace
its electrolytic capacitor every 10 years. When the filter capacitor’s electrolyte leaks,
safety valve bursts out or the capacitor main body expands, it shall be replaced
immediately.
5.3 Storage and Warranty
 Storage
If the controller is not used temporarily or stored for long time after purchasing,
please pay attention to the following points:
1. Avoid placing the controller in high temperature or humid and vibrating place or
with metal dust, ensure good ventilation.
2. When controller is long time no used, the internal filter capacitor performance will
decline. It is necessary to power on the controller every 2 years to restore the
performance of the filter capacitor, and the controller can be checked at the same
