When operating Vertiv products, the operation personnel must observe the safety rules in the industry, the
general safety points and special safety instructions provided by Vertiv.
1. The UPS must be installed, commissioned and serviced by engineers designated
by the manufacturer or its agent. Failure to observe this could result in personnel
safety risk, UPS malfunction and invalidation of warranty.
2. The UPS has been designed for commercial and industrial use only, and is not
recommended for use in life support applications.
3. This is a Class C2 UPS product. In a residential environment, this product may
nevertheless cause radio interference, in which case, the user is required to take
additional measures to reduce the interference.
4. The UPS is not recommended for use in special loads with DC component.
Backfeed protection
Before operating the circuit, isolate the UPS firstly and then check the dangerous
voltage between the ports, and that between the ports and earth.
Conformity and standards
The UPS complies with 2014/35/EU (LVD), 2014/30/EU (EMC), 2011/65/EU (Rohs)
and the following product standards for UPS:
IEC/EN 62040-1/AS 62040-1, General and safety requirements for UPS
IEC/EN 62040-2/AS 62040-2: Class C2 compliant
IEC/EN 62040-3/AS 62040-3 (VFI SS 111): Performance requirements and test
methods
The UPS installation should follow the above instructions and use the accessories
specified by manufacturer.
When the UPS is operating, some parts have high voltage, therefore, contacting
with them directly or through moist objects will result in fatal risk.

1. Before moving or rewiring the UPS, disconnect mains input power and the battery
and make sure that the UPS is completely shut down. Otherwise, the output terminal
may carry live voltage, presenting an electric shock hazard
2. Liquid or other irrelevant external objects are prohibited inside the UPS.
3. In case of a fire, a dry chemical fire extinguisher is essential. Using a foam fire
extinguisher will cause electric shock.
4. The output neutral line of the UPS is from the input, after the neutral line is
suspended by the upstream protection devices, the output neutral line will be
unconnected.
5. To prevent the radio frequency of output cables from disturbing other electric
equipment, we recommend using the UPS output cable with the length less than
10m.
High leakage current
1. Earth connection is essential before connecting the input power (AC mains and
battery included).
2. Earth leakage current not greater than 3.5mA.
3. Transient and steady-state earth leakage currents, which may occur when
starting the equipment, should be taken into account when selecting instantaneous
residual current circuit breaker (RCCB) or residual current detector (RCD).
4. Note that the earth leakage current of the load will be carried by RCCB or RCD.
5. This equipment must be earthed in accordance with the local electrical codes.
1. When selecting the UPS system upstream distribution protection equipment,
ensure that it complies with the local electric regulations.
2. The specified upstream breakers are required to obtain the conditional
short-circuit current rating, Icc at 10kA symmetrical rms. The specified upstream
breakers should comply with an IEC 60947 series standard.
User serviceable components
1. The UPS contains no user-serviceable parts. Do not remove the cover. Removing
the cover may result in electric shock and will invalidate any implied warranty.
2. The UPS meets the safety requirements completely in operator access area. Only
service personnel can contact the hazardous voltage inside the UPS. However, the
risk of contacting these voltages is minimized because the components with
hazardous voltage may be contacted only by using a tool to remove the protective
cover. No risk will exist if you follow the general norms and in accordance with the
procedures recommended in this manual on equipment operation.

Battery high voltage
1. All the physical service and maintenance of the battery are performed by the
trained technicians.
2. Operation on the battery will result in electric shock and high short-circuit
current, therefore, before operating the battery, the following should be observed:
Remove the watches, rings and other metal objects.
Use the tools with insulation handle.
Wear rubber glove and shoes.
Avoid placing the tools and metal objects on the battery surface.
Cut off the charge power supply before connecting or disconnecting the
battery terminals.
Check whether the battery is earthed accidently, if yes, please disconnect the
earthing. Contacting any earth battery parts will result in electric shock.
Therefore, make sure that the battery is not earthed during installation and
maintenance.
3. Battery manufacturers provide the details of the precautions to be observed
when working on, or in the vicinity of the batteries. These precautions should
always be followed implicitly. Attention should be paid to the recommendations
concerning local environmental conditions and the provision of protective clothing,
first aid and fire-fighting facilities.

Figure 1-4 UPS operating principle
1. The UPS consists of mains input (main and bypass), rectifier/PFC, charger, inverter, bypass, battery, DSP
controller, and output.
2. When the mains is normal, the rectifier will start, and the charger will charge the battery string. Before
turning on the UPS, the output voltage is bypass voltage, and the mains supplies power to the load through
the bypass. After turning on the UPS, the electronic transfer switch connects the inverter output to the load,
and the mains supplies DC power to the inverter through the rectifier/PFC circuit. The inverter then converts
DC power into pure sine wave AC power, and supplies the AC power to the load through the electronic
transfer switch.
3. When the mains is outside the UPS input supply tolerance levels, the battery supplies the required power
to the load through the rectifier/PFC circuit where the battery voltage is boosted, and then supplies to the
Inverter where it converts DC into pure sinewave AC power.
4. After the input mains returns within tolerance levels, the UPS will automatically transfer from Battery mode
to Normal mode, the mains supplies DC power to the inverter through the rectifier/PFC circuit, and then the
electronic transfer switch supplies AC power to the load.

1.5 UPS State and Operation Mode
For the LED indicators introduced in this section, refer to 4.1.1 LED Indicators.
The UPS state and operation mode include: Normal mode, Bypass mode, Battery mode, ECO mode, Fault
state and Maintenance Bypass mode. The operation schematic diagrams of Normal mode, Bypass mode,
Battery mode and Maintenance Bypass mode are shown in Figure 1-5 to Figure 1-7.
1.5.1 Normal Mode
When the mains input is normal, the load is supplied with voltage-stabilizing and frequency-stabilizing power
by the mains after processing of the rectifier and the inverter, and meanwhile, the charger is charging the
battery. The operation mode is Normal mode.
In Normal mode, the run indicator (green) is on, the alarm indicator is off, and the buzzer is silence.

1.5.2 Bypass Mode
If the overload overtime, inverter or rectifier failure appears during the UPS operation in Normal mode, the
UPS will transfer to Bypass mode, that is, 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 run indicator (green) is on, alarm indicator (yellow) is on, and the buzzer beeps every
second. The 'Current' page in LCD will display 'On Bypass'.

1.5.3 Battery Mode
Upon mains failure or voltage out of range, the rectifier and internal charger will stop running, and the battery
will supply power to the load through the inverter. In Battery mode, the run indicator (green) is on, alarm
indicator (yellow) is on, and the buzzer beeps every second. The 'Current' page in LCD will display 'On
Battery'.

1. The battery has been fully charged before delivery. However, some loss of
capacity is inevitable during transportation and storage. Therefore, it is important to
charge the battery for eight hours before the UPS is first put into operation to
ensure it can provide adequate backup time.
2. The Liebert ITA2 UPS supports cold start function, while this function is activated,
UPS can be powered using battery mode without availability of input power supply.
Therefore, the battery power can also be utilized independently for improving the
system availability.
1.5.4 ECO Mode (for UPS Equipped with Battery 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 power
equipment insensitive to power grid quality, you can use the ECO mode for power supply through bypass to
reduce the power loss.
1. In ECO mode, if the bypass failure or abnormal bypass voltage appears when the
output is not overloaded, the UPS will transfer to Normal mode. However, if the
bypass failure or abnormal bypass voltage appears when the output is overloaded,
the UPS will not transfer to Normal mode, but shut down the bypass.
2. In ECO mode, the efficiency of the UPS is up to 98%.
3. Only battery is available can the UPS enters ECO mode.
