Bypass Operation

During bypass operation, the critical load is supplied directly by utility power. A single-line diagram will appear on the screen with an orange line indicating the power flow through the Bypass SSW to the load.

CAUTION!

Do not open Q2 or Q5 when the UPS is in bypass operation, as this action may result in a load drop or a failure of the UPS to support the load.
