Safety Instructions
IMPORTANT SAFETY INSTRUCTIONS!
SAVE THESE INSTRUCTIONS!
This User Guide contains important instructions for your Powerware 5125 that must be followed
during installation and maintenance of the UPS and batteries.
The installation and use of this product must comply with all national, federal, state, municipal, or
local codes that apply. For assistance, call Powerware Service or your local Powerware office.
If the Powerware 5125 has been damaged during shipment, call your vendor immediately.
If the Powerware 5125 is stored, the batteries should be recharged every 6 months. If stored
above 25° Celsius, recharge the batteries more often.
CAUTION!
Whenever the Powerware 5125 is “On,” there may be dangerous voltage present at the unit’s
outlets. This is true because the unit’s battery supplies power even if the unit is not plugged
into the wall outlet. The unit contains dangerous voltages.
To reduce the risk of electric shock, install in a temperature-controlled and humiditycontrolled indoor area free of conductive contaminants.
The power supply cord is intended to serve as the disconnect device. The socket-outlet shall
be near the equipment and shall be easily accessible.
With the exception of the user-replaceable batteries, all servicing of this equipment must be
performed by qualified service personnel.
Before maintenance or repair, all connections must be removed. Before maintenance, repair,
or shipment, the unit must be completely switched off and unplugged or disconnected.

1.0 Powerware 5125 - One of the Best!
The Powerware 5125 uninterruptible power system (UPS) protects your sensitive electronic equipment from basic power problems such as power failures, power sags, power surges, brownouts,
and line noise.
Power outages can occur when you least expect it and power quality can be erratic. These power
problems have the potential to corrupt critical data, destroy unsaved work sessions, and damage
hardware - causing hours of lost productivity and expensive repairs.
With the Powerware 5125, you can safely eliminate the effects of power disturbances and guard
the integrity of your equipment. The Powerware 5125 was designed for critical applications such
as PC’s, servers, workstations, and telecommunications equipment. Figure 1 shows the
Powerware 5125 UPS with an optional Extended Battery Module (EBM)
Figure 1. The Powerware 5125

Providing outstanding performance and reliability, the Powerware 5125’s unique benefits include the
following:
• Advanced Battery Management Plus (ABM Plus
™
) doubles battery service life, optimises recharge
time and provides a warning before the end of useful battery life.
• Buck and Double Boost regulation ensures consistent voltage to your load by correcting voltage
fluctuations without using battery power.
• Hours of extended runtime with up to four EBMs.
• Hot-swappable batteries simplify maintenance by allowing you to replace batteries safely without
powering down the critical load.
• Start-on-battery capability allows you to power up the UPS even if utility power is not available.
• Advanced power management with the Software Suite CD for graceful shutdowns and power
monitoring.
• Sequential shutdown and load management through separate receptacle groups, called load
segments.
• Network Transient Protector guards your network communications equipment from surges.
• Optional X-Slot
™
modules provide enhanced communication capabilities for increased power
protection and control.

2.0 Installation
This section explains:
• UPS installation
• UPS rear panels
Installing the UPS
The following steps explain how to install the UPS. Figure 2 shows a typical installation only. See “UPS
Rear Panels” on Page 7 for the rear panel of each model.
NOTE Do not make unauthorised changes to the UPS, otherwise damage may occur to your
equipment and void your warranty
1. If installing an optional EBM, continue to Step 2; otherwise skip to Step 4
2. Plug the EBM cable into the battery connector on the UPS rear panel (See Figure 2).
3. If a second EBM is to be installed, plug the EBM cable of the second cabinet into the battery
connector on the first EBM. Up to four EBMs may be connected to the UPS.
Figure 2. Typical Installation with Two EBMs

4. If you are installing power management software, connect your computer to the UPS
communication port using the supplied communication cable.
5. Plug the detachable UPS power cord into the input connector on the UPS rear panel.
6. Plug the UPS power cord into a power outlet. The front panel indicators cycle through a startup
sequence while the UPS conducts a self-test.
When the self-test is complete, the indicator flashes, indicating the UPS is in Standby mode
with the equipment offline. If the alarm beeps or a UPS alarm indicator stays on, see Table 9 on
Page 25.
7. Plug the equipment to be protected into the appropriate UPS output receptacles (see page 15 for
more information on load segments).
DO NOT protect laser printers with the UPS because of the exceptionally high power
requirements of the heating elements.
8. Press and hold the ON button until you hear the UPS beep (approximately one second). The
indicator stops flashing and the bar graph indicators display the percentage of load being applied
to the UPS
The UPS is now in Normal mode and supplying power to your equipment.
NOTE The batteries charge to 90% capacity in approximately 3 hours. However, it is
recommended that the batteries charge for 24 hours after installation or long-term
storage.

3.0 Operation
This section describes:
• Operating modes
• Turning the UPS on and off
• Starting the UPS on battery
• Initiating the self-test
Operating Modes
Powerware 5125’s front panel indicates the UPS status through the UPS indicators. Figure 5 shows the
UPS front panel indicators and controls.
Figure 5. UPS Front Panel

9
Normal Mode
During normal mode the indicator illuminates and the front panel displays the percentage of UPS load
capacity being used by the protected equipment (see Figure 6). The UPS monitors and charges the
batteries as needed and provides power protection to your equipment.
When all the bar graph indicators and the indicator are illuminated, power requirements exceed UPS
capacity; see Page 25 for more information.
Buck and Double Boost Mode
With the Buck and Double Boost feature, the UPS accepts a wide input voltage range (-30%/_+20% of
nominal) and provides consistent, clean voltage to your equipment. The UPS operates normally from utility
power and alerts you of the voltage fluctuations. The indicator alternates between green and red while
in Buck, Single Boost or Double Boost mode as shown in Figure 7.
