Patent ID: 7057308

Claim:
An uninterruptible power supply (UPS) that provides power to a load, the UPS comprising: an input to receive input power from an input power source; an output that provides output power to a load; a DC voltage source that provides DC power, the DC voltage source having first and second terminals; an electrical circuit coupled to the DC voltage source, the electrical circuit capable of receiving the input power and providing the output power; a chassis for housing at least the DC voltage source and the electrical circuit; and a connect/disconnect assembly comprising: a first connect/disconnect portion; and a second connect/disconnect portion, the second connect/disconnect portion being configured to mate to the first connect/disconnect portion; and wherein the connect/disconnect assembly is coupled to the DC voltage source and constructed and arranged to be operable from outside the chassis, the connect/disconnect assembly having a first state wherein the DC voltage source is coupled to the electrical circuit through the connect/disconnect assembly and a second state wherein the DC voltage source is disconnected from the electrical circuit, the connect/disconnect assembly being coupled to the DC voltage source independent of whether the connect/disconnect assembly is in the first or second state, the connect/disconnect assembly being configured such that the first and second connect/disconnect portion are biased toward the second state.
