OPERATING INSTRUCTIONS

NORMAL MODE OPERATION

AC INPUT BATTERY UPS ON BYPASS

Normal Mode Operation at 26-50%

During normal operation, util- ity 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

AC INPUT BATTERY UPS ON BYPASS

Bypass Mode Operation at 26-50%

Bypass mode occurs when the OFF button is pressed once while the UPS is in Normal Mode. During bypass opera- tion, 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.

BATTERY MODE OPERATION

AC INPUT BATTERY UPS ON BYPASS

Battery Mode Operation at 80-61%

17

Battery mode occurs in event of an extreme input voltage condition or complete utility failure. The battery system supplies power through the DC to DC converter to the inverter to generate power for the connected load.
