Question

Quizplus · Accepted Answer

Inspection of cable connections is a common preventative maintenance activity for a UPS system as loose or corroded connections can cause voltage drops or failure. Battery impedance and voltage testing are also important for ensuring that the battery is functioning properly. Specific gravity tests for the glycol solution and shorting the output terminals are not typically part of UPS preventative maintenance activities.
