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 multiunit 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. For more
information, see Environmental specifications.
• 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 must 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 must be used when addressing this concern.
• Reliable earthing—Reliable earthing of rack-mounted equipment must be maintained. Particular attention
must 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 the
UPS input specifications.
Preparing the equipment
Procedure
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 HPE 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.
