Quarterly Maintenance

Quarterly maintenance

This maintenance will include and not limited for the following activities:

• Visual inspection of the UPS & Listening tests
• Main components visual check
• Check of environment, temperature, dust, moisture, room vents,
• Take all measurements from the UPS controller (input & output voltage, current, frequency…..)
• Check the history indicated alarms from the UPS controller.
• Functional checkout and test of the UPS diagnostic systems.
• Inspection of all power cabling for abrasions and burn spots, signs of overheating, swelling, leaking, etc.
• Examination of printed Circuit board alignments.
• Conduction of thermal scans on electrical connections to ensure all are tight and not generating heat, which is the first and sometimes only indication of a problem. A non-evasive diagnostic tool helps technicians identify hot spots invisible to the human eye.
• Measuring the nose level of the UPS and check for extra vibration.
• Control battery replacement: if the control batteries have been used without an inverter or bypass AC power, they may need replacement sooner.
• Testing the UPS transfer switches, circuit breakers, and bypasses.
• Battery operation and return.
• Check the running time on the three counters in the UPS ( through input power, through batteries & through bypass).
• Tracking record & forecasting coordinates with our software data base system .
• More--
• Provide computer analysis and historical archiving of all battery data and furnish an Quarterly Maintenance Routine Report.
