Where an Uninterruptable Power Supply (UPS) is used in a system to ensure highly reliable power supply to an electronic system, occasional maintenance or repair of the UPS or its storage batteries may be required. Effecting this servicing while ensuring that the utility power continues to be supplied to the load may involve a Maintenance Bypass Assembly (MBA) comprising a plurality of manually-operated circuit breakers. The possibility of an incorrect actuation of such circuit breakers is precluded by the coordination of a plurality of electromechanically actuated circuit breakers in communication with a controller that may store a table of permitted state transitions and sequences for safe operation. Such operation may be confirmed by one or more sensors monitored by the controller.

Storage batteries connected in series in an uninterruptable or back-up power supply system may have voltage potential differences between exposed terminals or conductors that exceed safety limits. A demountable insulating shield having apertures may be positioned so that the series string may be broken into a plurality of series sub-strings having a lesser potential difference has a cover over the aperture through which the series string configuration may be connected and disconnected. The cover may be an insulating material removably fastened to the insulating shield or a sliding cover that is captivated to the insulating shield. When the series string has been divided in to the sub-strings, the insulating shield may be demounted from the structure housing the batteries so that the batteries or their connections may be serviced.
