Overview
HP UPS R3000 ERM
Installation Instructions
The ERM consists of two battery packs in a 2U chassis. The
ERM connects directly to a UPS R3000 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.
For more information about any of the topics covered in this
document, see the UPS user guide located on the
documentation CD or HP website
(http://www.hp.com/go/rackandpower
).
Precautions
WARNING: A risk of personal injury from
electric shock and hazardous energy levels
exists. The installation of options and routine
maintenance and service of this product
must be performed by individuals who are
knowledgeable about the procedures,
precautions, and hazards associated with AC
power products.
This symbol indicates that the ERM
45 kg
100 lb
exceeds the recommended weight for
one individual to handle safely.
WARNING: To reduce the risk of
personal injury or damage to the
equipment, observe local occupational
health and safety requirements and
guidelines for manual material
handling.

Tools and materials
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.
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: If preparing the rails for integrated shipping,
follow the same instructions as in "Installing the UPS."
NOTE: Mounting hardware for square- and round-
holed racks is included in the UPS kit.
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.

2. Insert screws through the rack into the mounting rail and
the front of each mounting bracket.
3. Install cage nuts or clip nuts into the rear of the rack.
5. Tighten the hex nuts.
6. Install the rear stabilization bracket using hex nuts. Wait
until the unit is installed and the brackets are adjusted
before tightening the nuts.
4. Insert screws through the mounting rail into the cage nuts
or clip nuts.
Powering down the UPS
1. Shut down all load devices.
2. Press the Standby button to take the UPS out of Operate
mode. Power to the load receptacles ceases.
3. Disconnect the UPS from utility power.
4. Wait at least 60 seconds for the UPS internal circuitry to
discharge.

Installing the ERM
Before installing the unit, review and adhere to all warnings
provided in "Precautions (on page 1)."
WARNING: Uneven mechanical loading in
the rack may cause a hazardous condition.
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.
1. Install the mounting rails ("Installing the mounting rails"
on page 2).
2. With one person on each side, lift the chassis to rail
level and slide the chassis on the mounting rails.
3. Attach the chassis to the rack using the supplied screws.
Connecting the ERM to the UPS
NOTE: Before connecting an ERM to a UPS, remove
the label from the ERM connector.
Plug the ERM cable (1) in the socket (2) at the rear of the UPS.
NOTE: To install a second ERM, plug the cable from
the second ERM into the socket at the rear of the first
ERM. Up to two ERM units can be connected.

Charging the ERM batteries
Connect the UPS to a grounded utility power outlet. When the
UPS is plugged in, the unit automatically enters Standby mode
and begins charging the ERM batteries. Allow 24 hours for
the ERM to fully charge.

NOTE: For units factory-configured for 200 V or 208
V, the Site Wiring Fault function has been disabled. If
reconfiguring a 230 V unit to operate at 208 V, the
Site Wiring Fault function must be manually disabled.
NOTE: If the UPS firmware version is 2.00 or later,
follow the instructions in “Configuring the UPS.” If the
UPS firmware version is earlier than 2.00, or the ERM
cannot be configured from the UPS front panel, use
the ERM configurator tool. To update the UPS
firmware or download the ERM configurator tool, see
the HP website
(http://www.hp.com/go/rackandpower
).
After the ERMs are installed, place the UPS in Configure
mode, and use the UPS front panel controls and LED
indicators to configure the UPS for the number of attached
ERMs. Other UPS parameters that can also be configured are
the nominal utility voltage level and Site Wiring Fault
detection.
In Configure mode, the LED front panel display changes
function to enable modification of the UPS parameters. Each
LED is associated with a different parameter.

To change the UPS configuration parameters:
1. Place the UPS in Configure mode.
The LEDs associated with the currently configured
parameters illuminate. A flashing green cursor indicates
where you are in the configuration process as you scroll
through the available settings.
2. To change the nominal voltage, press the On button to
advance the cursor to the LED associated with the
appropriate nominal voltage parameter. The selected
voltage configuration LED flashes.
3. Press the Standby button to select the nominal voltage
configuration. The LED associated with the old input
voltage parameter turns off and the LED associated with
the new input voltage parameter illuminates solid green.
NOTE: Only one nominal utility voltage can be
configured. When setting voltage configuration
parameters, selecting an On value for any one
parameter automatically sets the other possibilities to
Off.
4. To enable the Wiring Fault parameter, press the On
button to advance the cursor to the Utility LED, then press
the Standby button. The LED illuminates solid green. This
parameter is disabled by default, and should only be
enabled for line-to-neutral connections. Enabling this
feature for line-to-line power sources will cause a false
alarm.

5. To configure the UPS for the number of connected ERMs,
press the On button to advance the cursor to the load
LED associated with the number of ERMs attached to the
UPS.
6. Press the Standby button to select the appropriate ERM
configuration. The associated LED illuminates solid
green.
7. To save the configuration settings and exit Configure
mode, press the Test/Alarm Reset button.
