HP UPS R5500 ERM
Installation Instructions
The ERM consists of two battery packs in a 3U chassis. The
ERM connects directly to a UPS R5500 or to another ERM. Up
to two ERM units can be connected.
At the HP recommended 80 percent load, one ERM extends
the available UPS runtime up to 30 minutes.

Tools and materials
Readying the equipment
The following tools are required for installation:
• Phillips screwdriver
• 10-mm hex-nut driver
The following items are supplied with the rack:
• Screws
• Hex nuts
• Cage nuts
• Cage nut-fitting tool
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" in the user guide.
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
1. Loosen the hex nuts, and extend the brackets to the
desired length.
for any reason.
NOTE: Mounting hardware for square- and
round-holed racks is included in the UPS kit.
