a) Cleaning, a visual inspection and a mechanical inspection of the UPS modules.
b) Replacement of defective parts or the preventive replacement of parts with a defined lifetime
c) “Updating” of the equipment (technical improvements subsequent to the delivery).
d) Check the calibration of DC voltage and Inverter Output Voltage and Frequency.
e) Check of the settings of the electronic regulation, the control and the alarm circuits of the
Rectifier(s) and Inverter(s).
f) Functional checks on Thyristors, Diodes, Transformers, Filter Components, e.g. to ensure that they
are operating within the specified design parameters.
g) Overall performance test including a Utility Failure simulation with and without the Load.
h) Monitoring
Battery operation in discharge and recharge mode including any boost charge duties.
