Safety Precautions
This manual contains the information concerning the installation and operation of the Vertiv™ Liebert®
ITA2 1-3 kVA UPS (hereinafter referred to as UPS). Please read this manual carefully prior to installation.
Please read the safety precautions very carefully before operating the unit in order to minimize the risk of
any accident. The words "Caution," "Note," and "Warning" used in this user manual and on the product do not
represent all the safety precautions to be observed and are only a supplement to the various safety
precautions. Therefore, installation and operation personnel must receive the required training and follow
the correct operations and all the safety points before operation.
When operating the Vertiv products, the operation personnel must observe the safety rules in the industry,
the general safety points, and special safety instructions provided by the Vertiv.

WARNING! The UPS must be installed, commissioned, and serviced only by the engineers
appointed by the manufacturer or its dealers. Failure to observe this could result in personnel
safety risk, UPS malfunction and invalidation of warranty.
WARNING! It is not recommended to use the UPS in life support applications as it is designed
primarily for commercial and industrial use.
WARNING! This is a Class C2 UPS product. It is recommended to take additional precautions
to minimize radio interference in a residential environment as this unit may continue to
generate radio interference.

Back feed protection
WARNING! Before operating the circuit, firstly, isolate the UPS and then check the dangerous
voltage between the ports, and finally check the dangerous voltage between the dangerous
voltage the ports and the earth.


Vertiv™ Liebert® ITA2 1-3 kVA User Manual

Conformity and standards
WARNING! 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 the manufacturer.
WARNING! When the UPS is operating, some parts have high voltage, therefore, contact with
them directly or through moist objects will result in fatal risk.
.
WARNING! 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
WARNING! Liquid or other irrelevant external objects are prohibited inside the UPS.
WARNING! In case of a fire, a dry chemical fire extinguisher is essential. It is prohibited to use
a foam fire extinguisher as it will cause electric shock.
WARNING! 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 unplugged.
WARNING! It is recommended to usea UPS output cable that is less than 10 meters in length
to prevent the radio frequency of the cable from affecting other electrical equipment.

High leakage current
WARNING! Earth connection is essential before connecting the input power (AC mains and
battery included).
Earth leakage current not greater than 3.5 mA.
Transient and steady-state earth leakage currents, which may occur when starting the unit,
should be considered when selecting instantaneous residual current circuit breaker (RCCB) or
residual current detector (RCD).
Note that the earth leakage current of the load will be carried by RCCB or RCD.
This unit must be earthed in accordance with the local electrical codes.

WARNING! When selecting the UPS system upstream distribution protection equipment,
ensure that it complies with the local electric regulations.
The specified upstream breakers are required to obtain the conditional short-circuit current
rating, Icc at 10 kA symmetrical rms. The specified upstream breakers should comply with an
IEC 60947 series standard.

Vertiv™ Liebert® ITA2 1-3 kVA User Manual

User serviceable components
WARNING! There are no user-serviceable components in the UPS. Do not remove the cover.
Removing the cover may result in electric shock and will invalidate any implied warranty.
The UPS must fully comply with all safety regulations in the operator access area. Only
trained technicians are permitted access to the dangerous voltage within the UPS. However,
the risk of contracting these voltages is minimized because the components with hazardous
voltage may be contacted only by using a tool to remove the protective cover. If you follow
the general guidelines and use the recommended methods in this manual, the risk will subside.

Battery high voltage
WARNING! All the hardware service and maintenance of the battery are performed by the
trained technicians.
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 to confirm whether the battery is accidentally earthed, and if so, disconnectthe
earthing.Contacting any earth battery parts will result in electric shock. Therefore, ensure
that the battery is not earthed during installation and maintenance.
Battery manufacturers provide the details of the safety precautions to be observed when
working on, or in the vicinity of the batteries, these precautions should always be followed
implicitly. It is recommended to pay careful attention to the local environmental conditions,
the provision of protective clothing, first aid, and fire-fighting facilities.
