Operation - Liebert 700-3000 VA User Manual

UPS On Indicator (Green)
The UPS On indicator is illuminated when the UPS inverter is operating and
supplying power to your connected loads.
Battery Indicator (Amber)The Battery indicator is illuminated when the UPS is
operating from the battery system.
AC Input Indicator (Green)
The AC Input indicator is illuminated when mains power is available and within
the input specification.
Output Voltage Selector Switches
The Output Voltage Selector Switches, located on the rear of the UPS, are
designed to allow selecting or changing the desired output voltage to match the
mains. The settings to choose from are 208, 220, 230, and 240 VAC output. The
factory default setting is 230 VAC.
NOTE: Never change the switch settings while UPS is on and powering
connected loads. Switch positions for voltages:
208 VAC
220 VAC
230 VAC
240 VAC
NOTE: Setting output voltage to 208 VAC will cause UPS unit to be derated to
90% of the VA and Watt rating listed in specification section.
NORMAL MODE OPERATION
During normal operation, mains power provides energy to the UPS. The filters,
the power factor conditioning 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 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 sound an alarm.
The display template indicates the percentage of load on the UPS output. Figure
1 displays approximately 51-75% loading.
