Modes of Operation

10.0MODES OF OPERATION

10.1Normal 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. The four green Load Level indica- tors display an approximate level of load in 25% increments. If the UPS becomes loaded beyond full rating, the fifth (amber) indicator will illuminate and the UPS will sound an audible alarm. The display template indicates the percent- age of load (see example at right) on the UPS output.

10.2Battery Mode Operation

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. During battery mode an alarm sounds every 10 seconds. This will change to two beeps every 5 seconds when the battery runs low (approximately 2 minutes remaining, but this is user configurable). The AC Input indicator will extinguish and the Battery indicator will illuminate to warn that a utility problem has occurred. Each Battery Level indicator repre- sents a 20% capacity level. As capacity decreases, fewer indicators remain illuminated. Refer to 13.0 - Trouble- shooting. For approximate battery run times, refer to Table 6 - Battery run times. These times are approximate

based on resistive load and an ambient temperature of 77°F (25°C). To increase this time, turn off non-essential pieces of equipment (such as idle computers and monitors) or add the optional external battery cabinet.

! CAUTION

Turning OFF the UPS while in battery mode will result in loss of output power.

10.3Battery Recharge Operation

Once utility power is restored, the UPS resumes normal operation. At this time, the Battery Charger begins recharging.
