What is a Bypass Switch?

Static Bypass switches are used to bypass the UPS normal operation, in cases of high inrush or fault conditions. Manual bypass switches are an added benefit to allow service and isolation for safety purposes. Correctly designed systems should enable these operations to be performed without loss of power to the load. External maintenance bypass switches add the facility to remove the UPS from site, offers local isolation capabilities and enables all ac cabling to be completed prior to the UPS delivery.
