Operating Instructions

9.0OPERATING INSTRUCTIONS

9.1Normal 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 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 (10% of load shown in example) on the UPS output.

9.2Battery 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 LED will extinguish,

and the Battery LED will illuminate to warn that a utility problem has occurred. Each battery level indicator represents a 20% capac- ity level. As capacity decreases, fewer indicators remain illumi- nated. Refer to 12.0 - Troubleshooting. For approximate battery

run times, refer to Table 5. 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 it is battery mode will cut off output power.

9.3Bypass 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.

9.4Battery Recharge Mode

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