A Break-Before-Make switch breaks the original connection before it makes a new one. If you turn a BBM
switch from “UPS” to “LINE,” the switch disconnects your protected equipment from UPS output power before
connecting the equipment to AC input power.
Best Power bypass switches that may be used for the Axxium Pro UPS are available in six models, as specified
in Table 10.
