HP UPS R1500 GENERATION 2 manual Installing the mounting rails, Readying the equipment

Page 12

•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 ("UPS input specifications" on page 36)" .

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.

Installing the mounting rails

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:

•The leveling feet are extended to the floor.

•The full weight of the rack rests on the leveling feet.

•The stabilizing feet are attached to the rack if it is a single-rack installation.

•The racks are coupled together in multiple-rack installations.

•Only one component is extended at a time. A rack may become unstable if more than one component is extended for any reason.
