3 Installation
Do not start the UPS until after the installation is finished, the system is commissioned by an authorized engineer, and the
external-input circuit breakers are closed.
WARNING! Risk of electric 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, verify with a voltmeter that power
is Off and wear appropriate, OSHA approved personal protective equipment (PPE) per NFPA 70E. Failure to
comply can cause serious injury or death. Before proceeding with installation, read all instructions. Follow all
local codes.
3.1 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
Vertiv representative immediately.
• Check the accessories included against the packing list. If there is any discrepancy, contact your local Vertiv
representative immediately.
CAUTION: The UPS is heavy (see Specifications on page65, for the weight). Take proper precautions when
lifting or moving the unit.
3.2 Pre-installation Preparation
Install the UPS indoors in a controlled environment, where it cannot be accidentally turned Off. The installation environment
should meet the specifications listed in Specifications on page65.
Place the UPS in an area of unrestricted air flow around the unit, away from water, flammable liquids, gases, corrosives, and
conductive contaminants. Avoid direct sunlight.
NOTE: Operating the UPS in temperatures above 77°F (25°C) reduces battery life.
3.2.1 Installation Clearances
Maintain at least 4 in. (100 mm) clearance in the front and rear of the UPS. Do not obstruct the air inlets on the front panel and
rear panel of the UPS. Blocking the air inlets reduces ventilation and heat dissipation, shortening the service life of the unit.
3.3 Installing the UPS
The UPS may be installed as a tower or in a rack, depending on available space and use considerations. Determine the type of
installation and follow the appropriate instructions. See Tower Installation on the next page or Rack Installation on the next
page.
NOTE: When installing the UPS or making input and output connections, comply with all relevant safety codes and
standards.
