1.3.4 Auto Restart Mode
When enabled, which is the default setting, Auto Restart Mode automatically restarts the UPS after a shutdown 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 overtemperature occurs, operation transfers to Bypass Mode.
When the UPS is in Battery Mode (with no bypass utility), and the inverter fails or overtemperature 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.
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 Liebert® ITA2 Maintenance Bypass Cabinet (MBC) is required for this mode. If your system includes a Liebert
ITA2 MBC, refer to the Liebert ITA2 MBC Installer/User Guide, available on the product page at www.Vertiv.com.

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.
1.3.7 Start up on Bypass Mode
Default : Disabled. When the inverter is in the soft start stage, the bypass mode will not be automatically triggered.
Change the startup on bypass via Paramset or the LCD settings page to enable.
When the DC bus soft start is completed, the bypass mode will be automatically triggered. If the inverter can enter the soft
start stage and the soft start is completed, the ups will automatically switch from bypass mode to normal mode.
When the DC bus soft start is completed, the bypass mode will be automatically triggered. If the inverter can not
automatically enter the soft start phase, the ups will always operate in the bypass mode.

If you do not install the UPSimmediately, 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 the 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 and 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 page18 , and Table 2.2 on page19 .
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.
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

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.
Vertiv™ Liebert® ITA2 Installer/User Guide
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 50.7lb. (23kg). The battery cabinets weigh
approximately 115lb(52.2kg)
The factory-provided, battery-to-battery power cables, see Figure 2.8 on page23 , connect the battery strings in parallel
to extend the backup time of the UPS. For 2U battery cabinets, you must adjust the DIP switch on the rear panel for each
cabinet in the string.

To connect power cables:
1.Verify that the battery breakers are in the open (Off) position before connecting or disconnecting battery
cables.
2. Depending on the type of battery cabinet, see Figure 2.10 on page26 , for 3U or Figure 2.11 on page28 , for
2U, and:
•Connect one end of a battery-to-battery cable to Connector B on the first cabinet in the first string
(Battery Cabinet 1), and the other end to Connector A on the first cabinet in the additional string (Battery
Cabinet 3).
•Connect one end of a battery-to-battery cable to Connector B on the second cabinet in the first string
(Battery Cabinet 2), and the other end to Connector A on the second cabinet in the additional string
(Battery Cabinet 4).
3. Verify that the connector colors align and press the cable in firmly to fully seat the connectors.
4. Tighten the captive screws on the extension cable to prevent the extension cable from loosening.
5. Connect an RJ-45 communication cable:
•On 3U strings, to Communication Port 2 on the first cabinet in the first string (Battery Cabinet 1), and the
other end to Communication Port 1 on the first cabinet in the additional string (Battery Cabinet 3).
•On 2U strings, connect a communication cable to Communication Port 2 and Communication Port 1
between each battery cabinet.
NOTE: If using both 2U and 3U battery cabinets in a system, you must manually configure the number of connected
battery strings via the display. The number of strings is not auto-detected.
NOTE: In a mixed-cabinet system, the communication cables allow temperature measurements. If your system is
running on an older version of firmware, you may need to set the multifunction port to "temperature" to enable the
measurements.
6. On 3U strings, close the battery output breaker(s).
– or –
On 2U strings, refer to Table 2.4 on the facing page , and Figure 2.12 on the facing page , and set the DIP

WARNING! Risk of electrical shock. Can cause personal injury and death. When connected together, battery
terminal voltage is potentially lethal. Be constantly aware that the battery system contains high DC and AC
voltages. Check for the presence of voltage using DC and AC voltmeters before making contact with
terminals.

Vertiv™ Liebert® ITA2 Installer/User Guide
A battery can present a risk of electrical shock and high short-circuit current. The following precautions should be observed
when working on batteries:
•Remove watches, rings and other metal objects.
•Use tools with insulated handles.
•Wear rubber gloves and boots.
•Do not lay tools or metal parts on top of batteries.
•Disconnect charging source prior to connecting or disconnecting battery terminals.
•Determine if the battery is grounded. If it is grounded, remove the source of the ground. Contact with any part
of a grounded battery can result in electrical shock. The likelihood of such shock will be reduced if grounds are
removed during installation and maintenance (applicable to a UPS and a remote battery supply not having a
grounded supply circuit).
The UPS is equipped with long-life, sealed, valve-regulated, lead-acid batteries (VRLA), also known as “maintenance-free”
batteries. The battery life depends upon the operating ambient temperature of the UPS system. To prolong battery life:
•Keep the ambient temperature between 59°F and 77°F (15°C and 25°C)
•Prevent long, low-current discharges.
•Charge the battery for at least 8 hours if the battery hasn't been charged for 3 months when it has been stored
at the specified ambient temperature, or 2 months when it has been stored at high ambient temperature
The waste lead-acid battery is dangerous waste material. Its storage, transportation, usage, and disposal must follow
national and local laws and other criteria about dangerous waste material and waste battery pollution prevention.
Per the applicable regulations, recycle the waste lead-acid battery. Other disposal methods are prohibited. Disposing of
the waste lead-acid battery in a landfill or other waste dump can result in serious environmental pollution and violates
national and local laws.
Vertiv has a service network and recycle system to assist in complying with laws governing waste battery disposal. Visit
http://www.Vertiv.com/en-us/support/ for information about recycling the waste battery.
