2 INSTALLATION
2.1 What's Included
•USB cable; one 2 m (6.5 ft) long
•Quick installation guide
•Safety and regulatory guidelines
•Tower support stands (2U and LI models only)
•Rack-mount rail kit (1U, 2U, and LI models only)
2.2 Unpacking and Inspection
Unpack the UPS and conduct the following checks:
•Inspect the UPS for shipping damage. If any shipping damage is found, report it to the carrier and your local
dealer or your Vertiv™ representative immediately.
•Check the accessories included in the packing list. If there is any discrepancy, contact your local dealer or your
Vertiv representative immediately.
2.3 Preparation for Installation
2.3.1 Installation Environment
•Install the UPS indoors in a controlled environment where it cannot be accidentally turned Off. The installation
environment should meet the conditions listed in Specifications on page37.
•Place it in an area of unrestricted airflow around the unit, away from water, flammable liquids, gases, corrosives
and conductive contaminants. Avoid direct sunlight.
•The socket outlet should be nearby and easily accessible.
•This UPS is not for use in a computer room as defined in the standard for the Protection of Electronic
Computer/Data Processing EquipmentANSI/NFPA75.
NOTE: Operating the UPS in temperatures above 77°F (25°C) reduces battery life.
2.3.2 Installation Clearances
Maintain at least 4 in. (100mm) clearance in the front and rear. Do not obstruct the air inlets on the front panel and rear
panel. Blocking the air inlets reduces ventilation and heat dissipation, shortening the service life of the UPS.
2 Installation 15

2.4 Installing the UPS
2.4.1 Installing a 2U or LI Model
The 2U UPS and optional battery cabinets may be installed in a tower or rack configuration. The LI models may also be
installed in a tower or rack configuration but do not support external battery cabinets. Determine the configuration that
meets your application needs, see Tower Installation below, or Rack-Mount Installation on the facing page.
Tower Installation
When using the UPS in a tower configuration, see Figure 2.1 below. If you have an external battery, see Figure 2.2 on the
facing page.
Figure 2.1 Attaching stands to the UPS
