Modes of Operation
2.0MODES OF OPERATION
The Nfinity Maintenance Bypass Cabinet is designed to operate in two modes: UPS Mode and Bypass Mode.
2.1UPS Mode
While the Nfinity Maintenance Bypass Cabinet is in UPS Mode, the UPS is supplying the connected load with continuous, high quality AC power. In this mode of operation, the load is protected by the UPS. The Bypass Switch rotated toward the green lamp indicates this mode.
2.2Bypass Mode
When the Nfinity Maintenance Bypass Cabinet is in the Bypass Mode, it provides an alternate path for power to the connected equipment. Should the UPS need to be taken out of service for limited maintenance or repair, manual activation of the bypass will cause an immediate transfer of the equip- ment from the UPS inverter to the bypass source.
The amber lamp illuminated in the Maintenance Bypass Switch compartment indicates bypass is available. In this mode of operation the load is NOT protected by the UPS. The Bypass Switch rotated toward the amber lamp indicates this mode. See 7.0 - Operation for instructions on use.
