Figure 1-3 Operating principle
1. The UPS is composed of mains input, I/O filter, rectifier/PFC, DC/DC charger, inverter, bypass, battery and UPS
output.
2. When the mains is normal, the rectifier will start, and the DC/DC charger will charge the battery strings. Before
turning on the UPS, the output voltage is the bypass voltage. After turning on the UPS, the electronic transfer switch
connects the inverter to the load, and the mains supplies DC power to the inverter through the rectifier/PFC circuit.
The inverter then inverts DC power to pure sine wave AC power and supplies AC power to the load through the
electronic transfer switch.
3. When the mains is abnormal, the rectifier/PFC circuit boosts the battery voltage and supplies it to the inverter. The
inverter then converts it into pure sine wave AC power, and supplies AC power to the load through the electronic
transfer switch.
4. After the mains returns to normal state, the UPS will automatically switch to Normal mode from Battery mode, the
mains power supplies DC power to the inverter through the rectifier/PFC circuit, and then the electronic transfer
switch supplies DC power to the load.
1.5 UPS State And Operation Mode
The UPS state and operation modes include: Normal mode, Bypass mode, Battery mode, ECO mode and Fault state.
For the description of indicators in this section, refer to Chapter 3 Operation And Display Panel for details.
1.5.1 Normal Mode
When the mains input is normal, the load is powered with voltage-stabilizing and frequency-stabilizing power supply
by the mains after processing of the rectifier and the inverter, and meanwhile, the operation mode that the charger
charges the battery is the Normal mode. In Normal mode, the inverter indicators are on (green).
1.5.2 Bypass Mode
If the overload is overtime, inverter or rectifier fails during the UPS operating in Normal mode, the UPS will switch to
Bypass mode, and the load is powered by the bypass source, which comes directly from the mains input; if the
rectifier is normal, the internal charger will charge the battery. In Bypass mode, the inverter indicators are off.
Note
In the event of the mains failure or mains voltage exceeds the specifications in Bypass mode, the UPS will shut down and stop the
output.
4 Chapter 1 Product Introduction
Liebert ITA 16kVA/20kVA User Manual
1.5.3 Battery Mode
Upon mains failure, rectifier overload or mains voltage exceeds the specifications, the rectifier and internal charger
will become inoperative, and the battery will supply power to the load through the inverter. The inverter indicators are
on and the buzzer alarms, which notifies you that the UPS is in Battery mode.
Note
1. The battery has been fully charged before delivery. However, transportation and storage will inevitably cause some charge loss.
Therefore, it is required to charge the battery for eight hours before putting the UPS into operation, so as to ensure the adequate
stand time for battery.
2. Battery cold start can also be used to start the UPS from the Battery mode (charged) upon mains failure. Therefore, the battery
power supply can be used independently for improving the system availability to some extent.
1.5.4 ECO Mode (For Single System Only)
In ECO mode, the load is powered by bypass when the bypass voltage is normal, and the load is powered by inverter
when the bypass voltage is abnormal. ECO mode is an energy-saving operation mode. For some power equipment
that insensitive to power grid quality, you can use the ECO mode for power supply through bypass to reduce the
power loss.
Note
1. In ECO mode, if the bypass failure or bypass voltage is abnormal when the output is not overload, the UPS will switch to Normal
mode. However, if the bypass failure or bypass voltage is abnormal when the output is overload, the UPS will not switch to Normal
mode, but shut down the bypass.
2. In ECO mode, the efficiency of the UPS is up to 98%.
1.5.5 Fault State
In Normal mode, the UPS will switch to Bypass mode when the inverter failure or the UPS over-temperature. In
Battery mode, the UPS will shut down and stop the output when the inverter failure or the UPS over-temperature. In
Fault state, the fault indicators will turn on, the buzzer will keep beeping, and the corresponding fault information will
be displayed on LCD panel.
Note
In Fault state, if the bypass failure or bypass voltage is abnormal when the output is not overload, the UPS will shut down and be
switched to the inverter for power supply, such as radiator over-hot. However, if the bypass failure or bypass voltage is abnormal
when the output is overload, the UPS will not switch to the inverter for power supply, but shut down the bypass.

Chapter 2 Installation 7
Liebert ITA 16kVA/20kVA User Manual
2.2.1 Distribution Room
The UPS is designed for indoor installation, which should be installed in clean and well- ventilated environment, so as
to keep the ambient temperature within the specifications range.
The internal fans provide the forced air cooling for the UPS. Cooling air enters the UPS through the front ventilation
holes, and exhausts the hot air through the back ventilation holes. Therefore, do not restrict the ventilation holes. The
front, rear and side panels of the UPS should be kept at least 200mm distance from the wall or consecutive
equipment, so as not to obstruct the UPS ventilation and heat rejection. Otherwise, the UPS internal temperature will
rise, which will shorten the UPS life.
If necessary, an indoor extractor fan should be installed to keep the indoor temperature from rising. An air filter should
be used where the UPS is to operate in a dirty environment.
Note
The UPS is only suitable for installing on the concrete surface or other non-flammable surface.
2.2.2 Battery Room
A small amount of hydrogen and oxygen will be produced at the end of battery charging, therefore, you must ensure
the fresh air ventilation of battery installation environment to meet the EN50272-2001 requirements.
The battery ambient temperature should be the constant temperature, because the ambient temperature is the main
factor to affect the battery capacity and life. The battery standard operating temperature is 20°C, operation above this
temperature will shorten the battery life, and operation below this temperature will reduce the battery capacity. If the
battery average temperature in run rises from 20°C to 30°C, the battery life will be reduced by 50%; if the battery
temperature in run exceeds 40°C, the battery life will be decreased exponentially. In general, the enabled ambient
temperature of the battery is 15°C ~ 25°C. The battery should be kept away from heat and ventilation holes.
When the UPS uses an external battery, you must install a battery protective device (such as fuse or circuit breaker),
and the battery protective device should be installed in areas near the battery, and the battery connection between
the alignment should be the shortest distance.
2.2.3 Storage
The UPS must be stored indoors to protect against excessive moisture or over-temperature environment, when the
UPS does not need to be installed immediately. The battery requires dry and low temperature, well-ventilated
environment for storage, and the most suitable storage temperature is 20°C ~ 25°C.
Warning: Battery Hazards
During the battery storage period, the battery must be periodically charged according to the battery instructions. You can connect
the UPS to the mains temporarily when charging the battery, so as to activate the battery for battery charge.
2.3 Installation tools
Prepare installation tools according to Table 2-1. The tools must be insulated and ESD-proof processed prior to use.
