The diagram in Figure 2 shows a static bypass switch connected across a UPS. The UPS. could be a double conversion or a delta conversion or rotary type. The static bypass switch. provides a means to accomplish high-speed transfer to the bypass path in case of UPS.
I have a UPS in my wife's home office with an illuminated building wiring fault light. This can apparently happen because of reversed polarity (it's not-at least not at this plug), missing ground, (it's there), and overloaded neutral. Switched neutral on circuit #1 (home office) light. - Wires stripped too far on circuit #2 light & plug. - Grounds at multiple outlets not wired to code, but possibly working properly. - Too many wires in multiple outlet boxes for no reason. None of this actually solved the problem.
