Getting Started

The Harsh Environment (HE) UPS system is shipped as two separate

cabinets (UPS Cabinet and Environmental Cabinet). Each cabinet is shipped
on a wood/foam and steel pallet. Use a forklift or pallet jack to move the packaged
cabinets to the installation site, or as close as possible to the site, before unloading
from the pallets.

This is the basic sequence of the installation steps:

1. Create an installation plan for the UPS and Environmental cabinets.

1. PrepareyoursitefortheUPSsystem.

2. Inspect, unpack, and unload the cabinets.

3. Wire the cabinets as applicable (Chapter 2).

4. Complete the Installation Checklist (Chapter 2).

5. Have authorized service personnel perform preliminary checks and startup.

After wiring the UPS system to the facility power and critical load(s), be sure to ground
the system according to local and/or national electrical wiring codes, using your own
cabling and conduit.

NOTE: Startup and operational checks should be performed only by authorized

service personnel. This service is usually offered as part of the sales
contract for your UPS system.

Creating an Installation Plan

Before beginning to install your UPS system, you should be sure you understand
the instructions in this manual. Use the procedures and illustrations in the
following sections to create a logical plan for installing the UPS system The
information in this chapter and Chapter 2 will help you plan the installation.

Preparing Your Site

For your UPS system to operate at peak efficiency, your installation site should
meet the environmental parameters outlined in this manual. If you intend to
operate the UPS at an altitude higher than 1500 meters (5000 feet), contact your
local sales or service office for important information about high altitude operation.
The operating environment must meet the size and weight requirements shown in
Table J of Appendix A.

The basic environmental requirements for operation of the UPS system are:

Ambient Temperature Range: 0 --- 5 0˚ C ( 3 2 --- 1 22 ˚ F)

Recommended Operating Range: 2 0 --- 2 5˚ C ( 6 8 --- 7 7˚ F)

Maximum Relative Humidity: 95%

The UPS and Environmental cabinets use forced air cooling to regulate internal
component temperature. Air inlets are on the right side of the Environmental
Cabinet and outlets are on the top of the UPS cabinet. You must allow clearance in
front of and above each cabinet for proper air circulation.

164291261 Rev. F 111503

2. Use a forklift or other material handling equipment to move the cabinets to a

convenient unpacking area. Insert the forklift jacks between the foam cushions
on the bottom of the unit.

CAUTION:
DO NOT tilt cabinets more than 10 degrees from vertical.

3. Set each pallet on a firm, level surface, allowing a minimum clearance of

4.6m (15 ft) on each side for removing the cabinets from the pallets.

4. Cut the steel bands around each cabinet.

5. Remove the protective cardboard covering from the cabinets, cutting where

indicated, using a knife blade no longer than 25 mm (1 in.).

NOTE: Do not discard the packaging material yet. Instructions for unloading the

cabinet from the pallet are printed on the cardboard, and you will need to
refer to them.

6. Remove the plastic bag and foam packing material, and discard or recycle

them in a responsible manner .

Unloading the UPS System From the Pallet

The UPS and Environmental cabinets are each bolted to sheet metal pallets
consisting of four supports secured to foam cushions. The foam cushions act as
shock absorbers for the cabinet during shipment.

WARNING:
UPS cabinets are extremely heavy. If unloading instructions are no t closely
followed, the cabinet may tip and cause serious injury.

T urning the jacking bolts unevenly may cause the cabinet to become
unbalanced. To prevent tipping, raise and lower the jacking bolts evenly. The
cabinet should only be raised approximately 3 mm (
(just enough to remove foam cushions).

1/8 in.) above the floor

1. Starting with the UPS cabinet, open and remove the cabinet door. Remove the

retaining screw located inside the door at the bottom hinge pivot point, then lift
the door off. Save the retaining screws for reinstallation of the door.

2. Locate the field kit (packed inside of the cabinet or communication panel).

Locate the four ½-in. jacking bolts and install them in the threaded holes in the
front and rear supports. Place a floor protector underneath each jacking bolt,
and screw the bolts down against them. The floor protectors will save the floor
from being marred by the jacking bolts.

3. Loosen, but do not remove the hardware holding the foam cushions to the

front and rear supports (labeled “1” in Figure 3).

4. Turn each jacking bolt consecutively, two full turns, until the foam cushions

clear the floor by approximately 3 mm (

Understanding UPS Operation

Your UPS functions automatically to supply AC electrical power to your

critical load. The UPS always operates in one of four modes:

• In Normal mode, the critical load is supplied by the inverter, which derives its

power from rectified utility AC power. In this mode, the rectifier also provides
charging current for the battery.

• In Battery mode, the battery cabinet provides DC power, which maintains

inverter operation. The battery supports the critical load.

• In Bypass mode, the critical load is directly supported by the utility through an

isolation transformer.

• In Maintenance Bypass mode, the critical load is directly supported by the utility

through a Maintenance Bypass circuit breaker..

The UPS continually monitors itself and the incoming utility power, and
automatically switches between Normal, Battery, and Bypass modes as required,
with no operator intervention. The Maintenance Bypass mode is a manual
operation needing operator intervention. The sophisticated detection and
switching logic inside the UPS ensures that operating mode changes are automatic
and transparent to the critical load. The UPS switches automatic operating modes
in response to these system events:

• A command is an intervention that is externally initiated by an operator or by

some site action. A command causes the UPS to switch operating modes; it
usually does not require any further action by you.

• A notice is a minor system event that may or may not require your attention.

• An alarm is a system event that requires immediate operator intervention.

System events, alarm horns, and indicator lights are described in Chapter 12 --­Responding to System Events.

Looking Inside the UPS

The Powerware BPIII HE is a continuous duty, solid-state UPS that supports the
following equipment: process control, data processing, and
telecommunications/PBX. The Powerware BPIII HE maintains power to the critical
loads during commercial electrical power brownout, blackout, overvoltage,
undervoltage, and out-of-tolerance frequency conditions.

In this manual, the power required by your equipment is called the critical load.The
UPS supplies the critical load with conditioned power that is synchronized with your
utility power. Figure 17 shows the main elements of the UPS.

If utility power is interrupted or falls outside the parameters specified in the Product
Specifications section of Chapter 16, the UPS uses a backup supply to sustain

power to the critical load for a specified period of time or until the utility power
returns. For extended power outages, the backup supply allows you to either
transfer to an alternative power system (such as a generator) or shut down your
critical load in an orderly manner.

The operation of the UPS system is described in greater detail in the following
paragraphs. The Product Specifications section of Chapter 16 outlines the storage
and operating specifications for the UPS.

164291261 Rev. F 111503

Normal Mode

In Normal mode, utility AC power is supplied to the rectifier. The rectifier supplies
DC power to the inverter, which then supplies the critical load with AC power. The
rectifier also provides charging power to the battery through a DC to DC voltage
converter. The battery charge condition is monitored by the UPS and reported by a
status indicator on the Monitor Panel. The message “System Normal” appears in
the s tatus area of the LCD screen.

Figure 18. Path of Current Through the UPS in Normal Mode

If the utility AC power is interrupted or is out of specification, the UPS automatically
switches to Battery mode to support the critical load with no interruption. When
utility power returns, the UPS returns to Normal mode.

If the UPS system becomes overloaded, the UPS switches to Bypass mode. The
UPS automatically returns to Normal mode when the error condition is cleared and
system operation is restored within specified limits.

Output

If the UPS suffers an internal failure, it switches automatically to Bypass mode and
remains in that mode until the failure is corrected and the UPS is back in service.

Bypass Mode

The UPS automatically switches to Bypass mode if it detects an overload, load
fault, or internal failure. The bypass source supplies the commercial AC power to
the load through an internal switch and an internal transformer.

CAUTION:
The critical load is not protected while the UPS is in Bypass mode.

You can transfer the UPS from Normal mode to Bypass mode manually. However,
the UPS switches automatically to Bypass mode whenever the inverter can no
longer supply the critical load. If the UPS transfers to Bypass mode from Normal
mode due to any reason other than operator intervention, the UPS automatically
attempts to transfer back to Normal mode (up to three times within a 10-minute
period).

Output

Bypass mode is a normal operating mode, and not an alarm condition. However, if
the UPS is unable to return to Normal mode following an automatic transfer to
Bypass mode, an alarm condition will be recorded.

Battery Mode

The UPS transfers to Battery mode automatically if a utility power outage occurs, or
if the utility power does not conform to specified parameters. In Battery mode, the
battery, through the DC to DC voltage converter, provides emergency DC power
that the inverter converts to AC power. When the UPS switches to Battery mode,
the alarm indications depend on the cause and condition of the battery charge.
The length of time the system can operate in Battery mode depends on loading
and the battery supply capacity.

When the discharging battery voltage reaches the lower limit of UPS operation
capability, the critical load transfers to Bypass mode if it is available. If Bypass input
is not available, a “Shutdown Imminent” warning occurs. The warning time before
critical load loss occurs is approximately 2 minutes, depending on battery capacity
and the amount of loading.

If incoming power returns to within specified parameters, the UPS automatically
returns to Normal mode and alarm indications clear. However, the process of returning
to Normal mode is not instantaneous. The rectifier gradually draws increasing power
from the incoming utility until Normal mode is achieved.

The UPS can be manually switched to Maintenance Bypass mode allowing the
UPS to be electrically isolated from the critical load. The bypass source supplies
the commercial AC power to the load through an internal circuit breaker.

Figure 21. Path of Current Through the UPS in Maintenance Bypass Mode

The wrap--- around maintenance bypass is useful during routine UPS maintenance
or repairs, by suppling utility power to the critical load while the UPS inverter and
bypass are de-energized.

The major components of the Maintenance Bypass are described in the following
paragraphs.

Maintenance Bypass (MBP) Circuit Breaker

This breaker is normally open. When closed, it feeds utility power to the critical load
when the MIS breaker is opened.

Maintenance Isolation (MIS) Circuit Breaker

This circuit breaker is normally closed, feeding UPS power to the critical load. This
breaker is opened to isolate the UPS after the MBP breaker is closed.

Maintenance Bypass (MBP) Circuit Breaker

This circuit breaker is normally closed feeding bypass power to the UPS internal
bypass circuit. This breaker is opened to isolate the UPS bypass after the load is
transferred to maintenance bypass.

Output

The MBP and MIS breakers are electrically interlocked to limit the possibility of UPS
system damage from improper operation.

• The BATTERY switch is a two-position rotary switch that allows you to manually

enable or disable the Battery Breaker CB2. The battery switch is also used to
reset the DC to DC converter if the converter shuts down during normal
operation.

• The PUSH TO RESET pushbutton is described in the “Resetting UPS System

after Emergency Power Off” section of this chapter.

• The START switch activates the power controls on the Control Panel. The

START switch is center-biased (the key will rest only in the upright position). Its

operation is similar to that of an automobile ignition switch. After setting the
operator controls, you turn the START switch to the right momentarily to
activate the controls. When you release it, it returns to the upright position.

The following paragraphs describe the controls and indicators found in the
Environmental cabinet (see Figure 33).

• The circuit breaker (CB1) switch supplies power to the rectifier and inverter. If

CB1 is on (closed), the rectifier turns on when the START switch is activated
and the proper voltage is at the input terminals.

• The circuit breaker (CB2) switch controls the application of battery power to the

UPS. If CB2 is closed, the rectifier charges the battery through the DC to DC
converter during normal operation. If utility power is lost, battery power is
supplied to the inverter through the DC to DC converter.

S Maintenance Bypass (MBP) Circuit Breaker --- T h i s b r e a k e r i s

normally open. When closed, it feeds utility power to the critical load
when the MIS breaker is opened.

S Maintenance Isolation (MIS) Circuit Breaker --- This circuit breaker

is normally closed, feeding UPS power to the critical load. This
breaker is opened to isolate the UPS after the MBP breaker is
closed.

S Bypass Input (BIB) Circuit Breaker --- This circuit breaker is

normally closed feeding bypass power to the UPS internal bypass
circuit. This breaker is opened to isolate the UPS bypass after the
load is transferred to maintenance bypass.

When the UPS system is running in Normal mode, it continually

monitors itself and the incoming utility power. In Battery or Bypass
modes, the UPS may issue alarms to let you know exactly what event caused the
change from Normal mode. System events can be indicated by horns, lights on
the UPS, or both.

Select Active from the Events menu on the LCD screen to look at the Active
System Events screen. This screen shows any currently active alarms, notices,
or commands.

System Event Horns

The system event horn beeps according to the type of event it is signifying:

• When the UPS detects an alarm that requires your attention, the horn beeps at

½-second intervals.

• When a notice occurs, the horn beeps at 2-second intervals.

• If the battery contactor is open and the Bypass mode is unavailable, the horn

beeps every 4 seconds.

Responding to System Events

System Event Lights

The status indicators on the UPS Monitor Panel work in conjunction with the event
horn to let you know when the UPS is operating in any mode other than Normal.
Only the Normal indicator is visible during normal UPS operation. The others light
to indicate alarms or events. When an alarm occurs, you should first check these
indicators to see what type of event has taken place. For descriptions of the status
indicators, see “Reading the Status Indicators” section of Chapter 9, “Using the
Monitor Panel”.

Connecting Equipment to a Serial Port

You can connect a wide variety of terminals, printers, and computers to each port,
and configure the UPS as the Data Communication Equipment (DCE). Set up the
remote equipment using the appropriate parameters for the mode you select. The
following section provides more information about configuration.

The cables you use for connection depend on the equipment you are connecting
to the UPS. Cables should be no longer than 16m (50 ft). The connectors for
Port 1 and Port 2 on the Communications Panel in the UPS are female, so the
cables should be male. Figure 41 shows the pin assignments for Port 1, and
Table 2 describes them. Figure 42 shows the pin assignments for Port 2, and

Configuring the Serial Ports

You must configure the port for communications using the LCD screen and
pushbuttons on the UPS Monitor Panel.

Select Port 1 or Port 2 (optional) from the Setup menu to display one of the Setup
Port screens. The screens for Port 1 and Port 2 are identical, and allow you to
specify settings for the two serial communication ports. Figure 43 shows the Setup
Serial Port 1 screen.

The operational mode of the port. Each communications port operates in one of
the following modes:

Te r m i n a l m o d e System events are logged immediately as they occur.

Calibration Used only by service personnel.

System Config. Allows you to set building alarms, battery tests, etc.

(Check with your Sales or Service Representative for availability.)

Computer Provides a proprietary Binary Computer Mode (BCM) Interface.

Remote Monitor Sends all system event information to an RMP, RIM, or

Supervisory Contact Module (SCM). Available for Port 1 only.

Port 1 and Port 2 cannot be in the same mode simultaneously; they must always be
operating in different modes. The modes are described later in this chapter.

The baud rate of the equipment connected to this port. The baud rate determines
the speed of data transferred between the UPS and the connected equipment. For
Remote Monitor mode, the baud rate must be set to 300. All other modes should
operate at the highest baud rate available with the connected equipment. 300
baud is not recommended for any mode except Remote Monitor.

You can select a baud rate of 300, 1200, 2400, 4800, 9600, or 19,200.

Data/Stop

The data size and stop bits of the equipment connected to this port. These
settings determine the number of bits transmitted per ASCII character. The data
size and stop bits you specify depend on the configuration of your equipment.

For Port 1, the data size must be set to 8, with 1 or 2 stop bits. Settings of 7 data
bits/1 stop bit and 7 data bits/2 stop bits are available for Port 2.

NOTE: When connecting a computer running a terminal emulation program, you

should set your equipment to NO PARITY.

Handshaking

This setting controls handshaking. You can select XON/XOFF or Disabled for this
setting.

Disabled (No Handshaking)

If handshaking is disabled, the UPS will transmit and receive data via the serial
port, ignoring all inputs from handshaking lines.

XON/XOFF

If handshaking is enabled, the UPS uses special characters (XON and XOFF) to
handshake with the host terminal. The XON character is defined to be ASCII value
11 hex, and the XOFF character is defined to be ASCII value 13 hex. Upon
reception of an XOFF command, the UPS halts transmission until an XON
command is received. In the same way, if the terminal receives an XOFF
command, the UPS expects the terminal to halt transmission until the UPS sends
an XON command.

Save

Set to YES to save any changes to configuration settings upon exit from the Setup
screen. Set to NO if you do not want to save any changes.

Default Settings

The following are the default configuration settings for the serial communications
ports:

Port 1 Remote Monitor 300 baud 8/1 Handshaking Disabled

Port 2 Terminal 9600 baud 8/1 Handshaking Disabled

Each communications port on the UPS operates in one of five modes which you
select when configuring the port using the Setup Port screen.

Term i nal Mo d e

In this mode, system events are continually logged through the serial port to the
device connected to the port. Port 2 operates by default in Terminal mode.

The printed log entries contain a time and date stamp and the alarm text message.
Terminal mode uses this format for printing alarm entries:

MMM DD HH:MM:SS.hh KYWD MESSAGE :::: <CF> <LF>

Symbol Description

MM Month (3 letters)
DD Day (2 digits)
HH Hour (2 digits)
MM Minute (2 digits)
SS Second (2 digits)
hh Hundredths of Second (2 digits)
KYWD Keyword (ALARM, NOTICE, COMMAND, or STATUS)
:::: System Diagnostic Information
<CF> Carriage Return Character (ASCII 13)
<LF> Line Feed (ASCII 10)

An alarm message is prefixed by the word “CLEAR” whenever an alarm is entered into
the Event History Log with a cleared status.

Printing Selected Information

If a port is operating in Terminal mode and is connected to a computer, you can
use key combinations at any time to print only selected information:

Ctrl+P Prints the entire log with a header

Ctrl+M Prints the current system meters with a header

Ctrl+A Prints all system information

Ctrl+B Prints Battery Test Log

To use a key combination, hold down the Control key and press the letter key.
