Selecting a site 
  WARNING:  To prevent fire or electric shock, install the unit in a temperature- and 
humidity-controlled indoor environment, free of conductive contaminants. 
When selecting a site, consider the following factors: 
 
Elevated operating ambient temperature—If the equipment is installed in a closed or multi-unit rack 
assembly, the operating ambient temperature of the rack environment might be greater than room 
ambient temperature. Install the equipment in an environment compatible with the operating 
temperature ("
 
Reduced air flow—In the rack, the rate of air flow required for safe operation of the equipment must 
not be compromised. 
 
Circuit overloading—Consideration should be given to the connection of the equipment to the supply 
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply 
wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing 
this concern. 
 
Reliable earthing—Reliable earthing of rack-mounted equipment should be maintained. Particular 
attention should be given to supply connections other than direct connections to the branch circuit, 
such as the use of power strips. 
 
Electrical requirements—All models require a dedicated (unshared) branch circuit, suitably rated for 
the specific UPS as stated in "Input specifications ("
 
Readying the equipment 
1.
 
Check the battery recharge date specified on the label that is affixed to the shipping carton. 
  IMPORTANT:  Do not use the battery if the recharge date has passed. If the date on the battery recharge 
date label has passed without the battery being recharged, contact an HP authorized service representative 
for directions. 
2.
 
Transport the packaged unit to its installation location. 
3.
 
Unpack the equipment near the rack where the unit will be assembled. 
  CAUTION:  Always plan the rack installation so that the heaviest item is on the bottom of the rack. Install 
the heaviest item first, and continue to populate the rack from the bottom to the top.
