Normal Mode Operation
During normal operation, mains 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.
Battery Mode Operation
Battery mode occurs in event of an extreme input voltage condition
or complete mains 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 mains 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 6. These times are approximate, based on resistive load and an ambient
temperature of 25°C (77°F). To increase this time, turn off non-essential pieces of equipment (such as
idle computers and monitors) or add the optional external battery cabinet.
Bypass Mode Operation
Bypass mode occurs when the OFF button is pressed once while
the UPS is in Normal Mode. During bypass operation, mains
power provides energy to the UPS. The mains 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.
Battery Recharge Mode
Once mains power is restored, the UPS resumes normal operation. At this time, the Battery Charger
begins recharging.
!
PERATING
CAUTION
Turning OFF the UPS while in it is battery mode will cut off output power.
