2 Judging Criteria
■
Whether there is liquid leakage.
■
Whether the safe valve has projected.
■
Measure the static capacitance.
■
Measure the insulating resistance.
3 Replacement
controller
Do not replace the electrolytic capacitor yourself. If replacement is required, contact
us.
8.4 Storage
For storage of the controller, pay attention to the following two aspects:
■
Pack the controller with the original packing box provided by Inovance.
■
Do not put the controller in the environment of high humidity or temperature, or
direct sunlight for a long time.
■
Long-term storage degrades the electrolytic capacitor. Thus, the controller must
be energized once every six months, each time lasting at least 5 hours. The input
voltage must be increased slowly to the rated value with the regulator.
