Normal Mode Operation
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 Operation
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.
!
CAUTION
Turning OFF the UPS while in bypass mode will result in loss of
output power.
