Industrial grade UPS, in contrast with IT (server) grade UPS, are generally installed in uncontrolled environment and fed from relatively poor quality electrical sources. They usually feed an unbalanced mix of industrial equipment and IT systems in a polluted and uncontrolled temperatures: ex. motors, lights, sensitive process equipment, telecom equipment, small servers, etc.
As a matter of fact in industrial plants, electrical sources usually have sever power quality issues due to the complexity of the other connected loads: Harmonics, unbalanced loading, voltage dips and sags, flickers, spikes and surges, over and under voltage, voltage variations, interruptions, frequency fluctuations, outages and short interruptions are few factors to be considered.
