1 PRODUCT DESCRIPTION
The Vertiv™ Liebert® ITA2 battery cabinet provides DC input power the Liebert ITA2 UPS. The battery cabinet may be
installed in a rack or tower configuration, and a maximum of five battery strings can be connected to the UPS.
When introduced, the battery cabinet was 3U height (U = rack units). Later, to reduce the rack space required by a Liebert
ITA2 UPS system, the battery cabinet was replaced by a 2U cabinet.

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 battery cabinets weigh approximately 115lb.(52.2kg).
2.1 Pre-Installation Preparation
Before beginning the installation, consider the environmental requirements, service clearances and external protective
devices for installing the equipment.
2.1.1 Environment of Installation Area
Install the UPS battery cabinet in an environment with the ambient temperature within the specifications listed in Table 2.1
below.
The environment must:
•Be clean and well-ventilated.
•Have no direct sunlight on the system.
•Be free from water, heat source and flammable and explosive substances.
•Be free from dust, volatile gases and corrosive materials.
Environmental Conditions Range
Operating Temperature, °F (°C) 32~122 (0 ~ 50)
Storage Temperature, °F (°C) -13 ~ 122) (-25 ~ 50)
Relative Humidity 5%RH ~ 95%RH (non-condensing)
Altitude, ft. (m) 9800 (3000), no derating
Table 2.1 Battery Cabinet Environmental Conditions
2 Installation 5

2.1.2 Installation Clearances
Maintain at least 4in.(102mm) clearance at the front, rear and side of the battery cabinet. Do not obstruct the air inlets on
the front panel and rear panels. Blocking the air inlets reduces ventilation and heat dissipation, shortening the service life of
the unit.
2.1.3 Installation Tools
IMPORTANT! All tools used to install and maintain the Liebert ITA2 battery cabinet and equipment must be
insulated.
The following tools are required to properly install your battery cabinet:
•Phillips-head screwdriver to install the rack rails
•Flat-blade screwdriver to install the battery cable
2.2 Equipment Handling and Unpacking
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 battery cabinets weigh approximately 115lb.(52.2kg).
During unpacking:
•Inspect the UPS for damage. If you find any problem, file a damage claim with the carrier immediately and
send a copy to Vertiv.
•Check the accessories and model numbers against the delivery list. If you find any problem, notify your local
Vertiv representative immediately.
2.3 Attaching and Removing the Bezel
To attach the bezel:
1. Obtain the bezel from the accessories package, and align the bezel with the front panel of the battery cabinet,
see Figure 2.1 on the facing page.
2. Press the fittings on both sides of the bezel into the rectangular holes on the battery cabinet.
To remove the bezel, grasp the sides and pull it away from the cabinet.

2.4 Tower Installation
1. Take the support bases out of the accessories box.
2. Connect the spacers and the support bases as shown in Figure 2.2 below. Each tower assembly requires
twosupport base/spacer assemblies, one in the front and one in the rear.
3. Place the UPS, battery cabinets and the MBC on the twosupport base assemblies.

2.5 Rack Installation
NOTICE
Risk of improper transport. Can cause damage to the UPS, MBC or battery cabinets.
Never attempt to lift or move the UPS, MBC or battery cabinets with the rack brackets. The brackets and
screws are not meant to lift the units.
NOTICE
Risk of improper installation. Can make rack top-heavy and cause a tipping hazard.
The battery cabinets are heavier than the UPS. Vertiv™ recommends installing the battery cabinets as near the
bottom of the rack as possible to maintain a low center of gravity. Install the UPS above the battery cabinets.
Install each unit on its own set of rack-mount guide rails. The rail kit will support the weight of a single UPS,
MBC or battery cabinet.
To mount the unit in the rack:
NOTE: Install the battery cabinets from bottom to top to minimize tipping hazard.
1. Referring to Figure 2.4 on the facing page, use four of the M4×10 screws on each bracket, and attach a
bracket to each front corner.
2. Referring to Figure 2.4 on the facing page, mount the right and left guide rails for each battery cabinet:
•Adjust the length of each guide rail to the dimensions of the rack.
•Align the install holes on the ends of the rail to the square holes in the rack, and use four of the provided
screws, two on each end to attach the rail to the rack.
3. Place the unit on the guide rails and push it completely into the rack along the guide rails.
4. Use M5×16 screws to secure the unit brackets to the rack, see Figure 2.4 on the facing page.
