HP Hewlett Packard Power Supply R5500 User Manual

Overview

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.

HP UPS R5500 ERM

Installation Instructions

At the HP recommended 80 percent load, one ERM extends

the available UPS runtime up to 30 minutes.

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.

personal injury or damage to the

equipment, observe local occupational

health and safety requirements and

guidelines for manual material

handling.

If the unit is to be shipped in an HP 9000 or

10000 series rack:

1. Remove the hex nuts, flat washers, and lock washers

from the mounting rail.

2. Install the rail reinforcement plates and tighten using the

hex nuts with captive washers included in the kit, instead

of the nuts included with the rail.

3. Install the rear mounting brackets 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.

3. Install the mounting ears on the chassis using the

screws provided.

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

WARNING: To prevent personal injury from

electric shock or damage to the equipment,

verify that the circuit breaker is in the

Off position.

4. With one person on each side, lift the chassis to rail

level and slide the chassis on the mounting rails.

5. Attach the chassis to the rack using the supplied screws.

6. If using the rear mounting brackets, be sure that the

Installing the ERM

Before installing the ERM, review and observe all warnings 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 of the carton, lift the

chassis and lower it to the floor in front of the rack.

Connecting the ERM to the UPS

Configuring the UPS

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.

Charging the ERM batteries

Connect the UPS to a grounded utility power outlet. When the

UPS is plugged in, it automatically enters Standby mode and

begins charging the ERM batteries. With the UPS in Standby

mode, allow the ERM batteries to charge for at least 24 hours

before putting the UPS into service.

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.

CAUTION: To ensure maximum runtime, be sure to

configure the UPS for the number of installed ERMs

using the UPS front panel controls.

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.

UPS front panel LED indicators

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 causes a

false alarm.

The front panel is shown with the bezel removed.

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.
