Inspection and maintenance
The inspection and maintenance of the power distribution cabinet depends on the frequency of use and the condition of the operating environment. If it is used for a long time or in a very hot or humid environment, the inspection and maintenance should be more frequent.
Inspection and maintenance should pay attention to the following aspects:
Every day:
(1) Check and clean the foreign objects around the power distribution cabinet.
(2) Check the working status of buttons and indicator lights.
(3) Whether the voltage and current are normal.
Monthly:
(1) Check whether the automatic and manual functions are normal and whether the indicator light is normally lit.
(2) Whether the crimping wire connecting screw is loose.
