UPS Maintenance Methods
UPS Visual Inspection
Regular visual inspection is the most important step in UPS maintenance. One can perform some basic visual inspections to check the appearance of the device. For example, check if there is any accumulation of dust or dirt. Dust or dirt can block the ventilation holes of the device and cause it to overheat. If there is, clean the dust with dry cloth or other insulative cleaning tools. Besides, the inspection should include battery evaluation as well. Please note if there are signs of corrosion, leakage or swelling, as these signs indicate that the battery needs to be replaced.
In fact, comprehensive visual inspections also include internal component inspections. For example, check whether the AC input & output capacitors and DC filter capacitors are clean to make sure there are no signs of cracking or expansion. However, one may get exposed to dangerous currents when doing such inspections. Therefore, such inspections can only be performed by qualified personnel, such as electrical engineers, facility electricians, or third parties.
In addition to visual inspection, one should also listen whether there are unusual sounds and pay attention to abnormal smells. Either of them may indicate the existence of hardware problems.
