Vertiv Liebert Nfinity''s Nfinity Maintenance Bypass Cabinet provides complete "wrap around" protection and allows the UPS to be pulled from service without interrupting power to the loads. The Maintenance Bypass Cabinet controls are located behind a lockable front panel to provide operation security. Controls include a manual bypass transfer switch, UPS input disconnect switch, and a branch rated output circuit breaker. Indicator lamps provide visual confirmation that the UPS Input, UPS Output, and Bypass Source are available. The Maintenance Bypass with Transformer option provides isolation in the bypass path as well as total flexibility with utility voltages. The transformer provides simultaneous output voltages of 120/120/208/240V regardless of whether the input voltage is 208 or 240V.
