3.3.1 Tower Installation
To install the UPS as a tower:
1. Take the support bases out of the accessories box.
Figure 3.1 Support Bases
Item Description
1 Support bases
2 Spacers with connectors
2. If optional, external battery cabinets will be connected, take out the spacers shipped with the battery cabinet.
3. Connect the spacers and the support bases as shown in Figure 3.1 above. Each Vertiv™ Liebert® GXT5 requires 2
support bases, one in the front and one in the rear.
4. Place the Liebert® GXT5 and any battery cabinets on the 2 support bases.
3.3.2 Rack Installation
When installed in a rack enclosure, the Liebert® GXT5 UPS and external battery cabinets (EBC) must be supported by a shelf
or rack-mount rails. Because different rack-mount options install in various ways, refer to the installation instructions provided
with the rack-mount kit.
CAUTION: The Liebert® GXT5 is heavy. The UPS must be installed as near the bottom of a rack as possible. If
placed too high, it can make the rack top heavy and prone to tipping over. For unit weights, see
Specifications on page85.
3.4 Installing External Battery Cabinets
Optional, external battery cabinets (EBC) may be connected in parallel to the UPS to provide additional battery run time. For
approximate battery run times with additional EBCs, see Battery Run Times on page99. External battery cabinets are placed
on one side of the UPS in a tower configuration or stacked beneath the UPS in a rack configuration. Up to 10 EBCs may be
connected to the UPS, and up to 6 may be detected using EBC auto-detection.
For applications where the number of EBCs exceeds 6 or for legacy applications where EBC auto-detection is not possible,
please contact Vertiv service for assistance.
