If the installation includes a Maintenance Bypass Panel, bypass mode and test mode will also be available. Normal operation During normal operation, the UPS converts utility power to conditioned power for the connected load. Battery operation During battery operation, the UPS provides power to the connected load from its internal and (if applicable) external batteries for a finite period. The UPS transfers to battery operation if the supply of utility power fails, or is outside pre-defined limits. Bypass operation (or static bypass operation) Static bypass operation can either be obtained by user request or automatically, as the UPS will switch into bypass operation if both the normal and battery operation modes are unavailable. During static bypass operation, the utility power is sent through internal Radio Frequency Interference (RFI) filters to the connected load, bypassing the internal power converters. The UPS transfers to bypass operation following a command received via the display, or after a short or heavy overload on the output of the UPS. Battery back-up is not available in bypass operation. Mechanical bypass In mechanical bypass, utility power is sent directly to the connected load through a mechanical breaker, bypassing all internal UPS functions and filters. Mechanical bypass is obtained by the operation of the mechanical bypass lever located behind the front cover. Mechanical bypass is a feature designed to keep the load supplied with utility power at maintenance of the power sections of the UPS. All major maintenance operations can be performed with the UPS running in mechanical bypass, and with the load being supplied directly with unconditioned utility power. 14 Smart-UPS® VT ISX 20-30 kVA, 208/220/480V Operation Operation Procedures Turn into mechanical bypass using the Mechanical Bypass Lever The load is not protected by the UPS when the internal mechanical bypass system is active, and, the power is not conditioned. Caution If the UPS is running and controllable through the display, carry out steps 1 through 6. If not, go directly to step 4. Note

Green and yellow LEDs are ON.  Turn the Mechanical Bypass Lever downwards into horizontal position.  Close the front door. Verify UPS is in normal operation. Yellow LED turns OFF and green LED remains ON. 16 Smart-UPS® VT ISX 20-30 kVA, 208/220/480V Operation Configuration Connection of Load to the PDU The Power Distribution Unit (PDU) at the rear of the UPS has six 3-phased breaker sets. The top 4- pole breaker set operates as a unit and protects any 3-phased equipment that may be connected to the PDU. This breaker unit will switch ON/OFF all 3 phases when operated (may supply several loads). Each of the 5 other breaker sets protects the 3-phased outlets beneath the actual breaker set. Connecting the load to the PDUs Connect the load evenly between the 3 phases to avoid overloading the PDU. The total output capacity of the PDU is approximately twice the output capability of the UPS. This means that UPS would be over-loaded if all PDU outlets were loaded to their

Note Note Note rating. Load status on the individual phases can be found through the UPS display or through the web interface. Equipment connected to the 3-phased output may require overcurrent protection with a lower rating than the 3-phased output. For 3-phased output, the highest current may be in the Neutral conductor at non-linear loads (up to 173%).
