Emerson GXT2U User Manual

During normal operation, utility 

power provides energy to the 

UPS. The filters, power factor 

correction circuit and the 

inverter process this power to 

provide computer grade power to 

connected loads. The UPS 

maintains the batteries in a fully 

charged state.
The four green load level LEDs 

indicate an approximate level of load in 25% increments. If the UPS becomes 

loaded beyond full rating, the fifth (amber) LED indicator will illuminate and 

the UPS will sound an audible alarm. The display template indicates the 

percentage of load (26-50% of load shown in the example above) on the UPS 

output.

Bypass mode occurs when the 

OFF button is pressed once 

while the UPS is in Normal 

Mode. During bypass operation, 

utility power provides energy to 

the UPS. The utility power 

bypasses the inverter and 

provides power for the connected 

load.
The four green load level LEDs 

indicate an approximate level of load in 25% increments. If the UPS becomes 

loaded beyond full rating, the fifth (amber) LED indicator will illuminate and 

the UPS will sound an audible alarm. The display template indicates the 

percentage of load (26-50% of load shown in the example above) on the UPS 

output.

Turning OFF the UPS while in bypass mode will result in loss of 

output power.
