Claim:
1. A method of operating a UPS system having a first UPS, the method comprising: receiving, at an input of the first UPS, input power from a power source; generating, with a first analysis circuit within the first UPS, a first signal containing information indicative of a signal characteristic of the input power received by the first UPS; receiving, at the first analysis circuit, a second signal from a second analysis circuit of a device coupled to the power source, the second signal containing information indicative of a signal characteristic of input power received by the device; analyzing, with the first analysis circuit, the first signal from the first analysis circuit of the first UPS and the second signal from the second analysis circuit of the device; determining, in response to analyzing the first signal and the second signal, whether an improper wiring condition exists at the input of the first UPS; in response to a determination, based on the analysis of the first signal and the second signal, that an improper wiring condition does not exist at the input, providing output power to an output of the first UPS; and in response to a determination, based on the analysis of the first signal and the second signal, that an improper wiring condition does exist at the input, de-energizing the first UPS.
