7.0 OPERATING INSTRUCTIONS
7.1 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
(26-50% of load shown in the example above) on the UPS output.
7.2 Bypass Mode Operation
Bypass mode occurs when
the OFF button is pressed
once while the UPS is in Nor-
mal Mode. During bypass
operation, mains power pro-
vides 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.
!
CAUTION
Turning OFF the UPS while in bypass mode will result in loss
of output power.
