Operating Instructions

6.0OPERATING INSTRUCTIONS

6.1NORMAL 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.

AC INPUT BATTERY UPS ON BYPASS

Normal Mode Operation at 26-50%

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.

6.2BYPASS 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. AC INPUT BATTERY UPS ON BYPASS The utility power bypasses

the inverter and provides

power for the connected load. Bypass Mode Operation at 26-50%

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.
