2.3.2. Rack Installation

When installed in a rack enclosure, the 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 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

2.4. Installing External Battery Cabinets
