Safety Precautions
This manual contains the information concerning the installation and operation of Liebert®
ITA2TM 30kVA UPS (hereinafter referred to as UPS). Please read this manual carefully prior to
installation.
To reduce the chance of accident, please read the safety precautions very carefully before
operation. The 'Caution, Note, Warning' in this user manual and on the product do not
represent all the safety points to be observed, and are only supplement to various safety
points. Therefore, the installation and operation personnel must receive strict training and
master the correct operations and all the safety points before operation.
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.
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.
V

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, it is recommended to use 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 ranges from 3.5mA to 100mA.
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 with 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.
VI

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 to place 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 batterys. These precautions should be
followed implicitly at all times. Attention should be paid to the recommendations
concerning local environmental conditions and the provision of protective clothing,
first aid and fire-fighting facilities.

1.4 Operating Principle
The operating principle of the UPS is shown in Figure 1-4.
Figure 1-4 UPS operating principle
1. The UPS is composed 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 1-8.
Maintenance bypass mode is activated only when the UPS output power distribution
unit (POD in short) is selected.
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 seconds. The 'Current' page in LCD will display 'On Bypass'.

In case of mains failure or mains voltage out of range in Bypass mode, the UPS will
shut down and stop the output
