1.3.4 Auto Restart Mode
When enabled, which is the default setting, Auto Restart mode automatically re-starts the UPS after a
shut-down that resulted from depleted batteries after an extended power outage. A built-in 10-second
delay after utility power is restored allows other equipment to start first and stabilize before the UPS
restarts.
1.3.5 Fault State
When the UPS is in Normal mode and the inverter fails or UPS over-temperature occurs, operation
transfers to Bypass mode. When the UPS is in Battery mode (with no bypass utility), and the inverter fails
or over-temperature occurs, the UPS shuts down and stops output power. During a Fault state, the front-
panel display alarm indicator (red)is On, the buzzer beeps continuously, and fault information displays on
the LCD screen.
1.3.6 Maintenance Bypass Mode
Used when the UPS requires maintenance or repair, Maintenance-bypass-mode operation powers the
connected equipment with utility power while electrically isolating the internal UPS components.
The optional, ITA2 Maintenance Bypass Cabinet (MBC) is required for this mode. If your system includes
an ITA2 MBC, refer to the Liebert® ITA2™ MBC™ Installer/User Guide, available on the product page at
www.Vertiv.com.
NOTICE
Risk of power interruption. Can damage the connected equipment.
If utility power fails or if its quality is out of range while the UPS is in Maintenance Bypass Mode,
the UPS may shut down without notice and shut-off output power to the load.
NOTE: The UPS has no user-serviceable parts. If the UPS malfunctions and requires service, visit
http://www.Vertiv.com/en-us/support/ or contact your local Vertiv representative.

2 INSTALLATION
Installation must be performed by properly-trained and qualified personnel. Do not start the UPS until
after the installation is finished, and the system is commissioned by an authorized engineer.
WARNING! Risk of electrical shock. Can cause property damage, injury, and death. The unit has
several circuits that are energized with high DC and AC voltages. Check for voltage with both
AC and DC voltmeters before making contact and before working within the UPS. Only properly
trained and qualified personnel wearing appropriate, OSHA-approved personal protective
equipment (PPE) should prepare for installation, install, and maintain the equipment. When
performing maintenance with any part of the equipment under power, service personnel and
test equipment must stand on rubber mats.
WARNING! Risk of electrical shock. Can cause equipment damage, injury and death. Before
beginning installation, verify that all external overcurrent protection devices are open (Off), and
that they are locked-out and tagged appropriately to prevent activation during the installation.
After the power cables are connected, the terminal block’s protective cover must be reinstalled
to remove the electric shock hazard.
WARNING! Risk of heavy unit falling. Improper handling can cause equipment damage, injury,
and death. Exercise extreme care when handling unit cabinets and rack-mounted units to avoid
equipment damage or injury to personnel. The UPS weighs approximately 50.7lb (23kg).
NOTE: The UPS can be connected to three-phase, five-wire (A, B, C, N, PE) TN, TT and IT AC power
distribution system (IEC60364-3).
2.1 Pre-installation Preparation
Before beginning the installation, consider the environmental requirements, service clearances, and
external protective devices for installing the equipment.
2 Installation 11

2.1.1 Environment of Installation Area
Install the UPS in a clean, well-ventilated environment with the ambient temperature within the
specifications listed in 6on page63.
The environment must:
•Have convenient wiring.
•Have adequate access for operators.
•Be clean and well ventilated.
•Be free from water, heat source, and flammable and explosive substances.
•Be free from dust, volatile gases, and corrosive materials.
•Comply with local fire-code regulations.
2.1.2 Installation Clearances
Internal fans provide forced-air cooling for the UPS. Cooling air enters through the front panel and hot air
is exhausted through the back. Maintain at least 8 in.(200mm) in the front and rear of the UPS, see
Figure 2.1 below.

2.1.3 Installation Tools
IMPORTANT! All tools used to install and maintain the ITA2 UPS and equipment must be insulated.
The following tools are required to properly install your UPS:
•Torque wrench
•Slotted screwdriver
•Multimeter
•#3 Phillips-head screwdriver
•T10 Torx screwdriver
2.1.4 Storage
If you do not install the UPSimmediately, you must store it indoors and protect it from excessive moisture,
heat, and other harsh conditions. Store the batteries in a dry, well-ventilated environment with a
temperature range of 68°F ~ 77°F (20°C ~ 25°C).
NOTICE
Risk of failure to properly charge batteries can damage the batteries and void the warranty.
Batteries will lose charge during storage. Batteries must be recharged as recommended by the
battery manufacturer every 3 to 6 months, depending on storage temperature:
•At 68-77°F (20-25°C): charge after 6 months in storage
•At 78-86°F (26-30°C): charge after 3 months in storage
•At 87°F or higher (31°C or higher): charge after 1 month in storage.
2.1.5 External Protective Devices
Circuit breakers or other external protective devices must be installed on the UPS input. The following
sections provide general guidance for installation by properly-trained and qualified personnel.
Rectifier and Bypass-input Protection
Overcurrent Protection—Install an appropriate overcurrent protective device should on the utility input
power distribution. Consider the current capacity of power cables and the system-overload requirements
in selection of the input protection and wiring, see Table 2.1 on page20, and Table 2.2 on page20.
Dual-Input System Protection—In a dual-input system, install separate protective devices for the utility
and bypass at the utility input power distribution.
Utility/Bypass Back-Feed Protection—the UPS includes back-feed protection in the event of a fault.
2 Installation 13

Earth Leakage Current—the residual current detector (RCD) for the UPS upstream input power
distribution should be:
•Sensitive to the DC unidirectional pulse (Level A) in the power distribution network
•Insensitive to the transient current pulse
•General sensitivity type, settable: 0.3A ~ 1A
The residual current circuit breaker (RCCB) must be sensitive to the DC unidirectional pulse (Level A) in
the power distribution network, but insensitive to the transient current pulse, see Figure 2.2 below.
Figure 2.2 RCCB symbols
When using the earth RCD in a split-bypass system, the RCD should be installed at the upstream input
power distribution end to prevent false alarms.The earth leakage current fed by the RFI filter in the UPS
ranges from 3.5mAto100mA. We recommend that you verify the sensitivity of each differential device of
the upstream input power distribution and downstream power distribution (to load).
Battery
The UPS includes an overcurrent-protection device for the battery.
UPS Output
The UPS includes output overcurrent protection in all modes of operation. If the customer-provided
output-distribution panel is not within sight of the UPS, the distribution panel must include a main
breaker.
