representative immediately.
Connecting One Battery Cabinet
Do not reverse the polarity of the battery cables. Before replacing the battery cabinet and connecting the battery
cables, ensure the battery breaker on the rear of the battery cabinet is open (Off).
Installing Battery Insulating Plates
The battery terminals need insulating plates to guarantee the sufficient
insulation distance between the battery external cables connection to
protect against faults such as arcing and short circuits.
To install the insulating plates:
1. Crimp the user external cable on the battery terminals.
2. Crimp the battery insulating plates, and use the screws to fasten the OT terminals
and insulating plates together onto the terminal block.
Installing the Battery Cabinet—Connecting Battery Cabinet Cables
When more than one string is installed, use the factory-provided cable to connect the battery cabinets, use the
factory-provided cable shown in Figure 1, Terminals A of the first string connects to the UPS. Terminal B of the
first string will connect to Terminal A of the second string.
Figure 1 Cables between Liebert ITA2 and battery cabinets
NOTE
The installation sequence of the OT terminals and insulating plates must be strictly observed, otherwise the
user external cables connection will be separated.

Connecting Additional Battery Cabinets
The factory-provided extension cable has a PP45 connector on each end, as shown in Figure 3. It connects the
battery strings in parallel to extend the backup time of the UPS. The factory-provided communication cable has
an RJ-45 terminal on each end for communicating with the battery cabinets.
Figure 3 Battery extension cable
To connect power cables:
1. Verify that the battery breakers are in the open (Off) position before connecting or disconnecting battery cables.
2. If the Liebert ITA2 UPS has been connected to a battery cabinet, remove the connection cables.
3. Connect the extension cable to the corresponding battery ports on the two battery cabinets. 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 the communication cable to the RJ-45 port on the battery cabinet to the UPS as shown in Figure 2.
Figure 2 shows two battery strings connected in parallel.
To connect the battery cabinets to the Liebert ITA2 UPS, refer to the UPS user manual, SL-00030, which
shipped with the UPS and is available at Vertiv’s Web site:
