1. Cleaning the UPS
Moisten a soft cloth with water or detergent, squeeze it tightly, and wipe the product lightly.
Do not use chemicals such as thinner and benzene. (They cause deformation or discoloration.)
2. Removing dust from the AC input plug, power supply output receptacles,
input terminal block, and output terminal block of the UPS
Stop all the connected devices and the UPS and disconnect the AC input plug from a wall outlet
(commercial power).
Then, remove dust with a dry cloth and make the connection again.
