PREFACE
ACE SERIES RACK-MOUNT
— ONE OF THE BEST!
Congratulations on selecting the ACE Series Rack-Mount
uninterruptible power system (UPS) to protect your sensitive electronic
equipment from power disturbances and dirty power.
Because a power outage can occur when you least expect it —
threatening the loss of critical data — it’s important to protect your
network with a full-featured UPS such as the ACE Series Rack-Mount.
Network administrators often spend countless hours trying to
troubleshoot problems that, in many cases, would never have oc curred
had a UPS protected their network.
Properly installed, a UPS can be the single most cost-effective measure
you can take to ensure system security. Providing outstanding
performance and reliability, the ACE Series Rack-Mount’s unique
benefits include the following:
Advanced Battery Management (ABM™) doubles battery service
life, optimizes recharge time, and provides a warning up to 60 days
before the end of useful battery life.
Hot-swappable batteries simplify maintenance by allowing you to
safely replace batteries without powering down your critical load.
Network and modem protection (may not be available on your
model) guards your modem, fax machine, and other network
communications equipment from surges.
Buck and Double Boost regulation ensures consistent voltage to
your load by correcting voltage fluctuations without using battery
power.
Start-on-battery compatibility allows you to power up your UPS
even if utility power is not available.
Our power management software is fully compatible with the ACE
Series Rack-Mount and provides sequential orderly shutdown of all
network devices including multiple servers and workstations.
Optional power communication cards provide enhanced
communication capabilities for increased power protection and
longer battery backup times.

NOTE
use caution when you handle and interconnect the units.
If operating the UPS while it is unplugged from the source of electrical power, DO NOT make contact
with the line cord input pins. Electrical shock hazard exists.
To reduce the risk of fire or electric shock, install in a temperature- and humidity-controlled indoor area
free of conductive contaminants.
(VDE requirement) The sum of earth leakage current from all loads connected to the UPS must not
exceed 1.5 mA.
Mounting the UPS in a Rack
The UPS fits in a 19-inch rack. Follow the steps below to install the UPS
in the rack.
The UPS is heavy. It can be very awkward, and potentially dangerous, to handle. Therefore, it is mandatory
that a minimum of two people lift and place the UPS in its rack.
Disconnect all cables from the UPS before continuing. Remove all self-adhesive pads from the underside of
the unit, if already fitted.
1.Place the unit on a hard, flat surface with the front of the unit
facing toward you.
4 Section 1 • Installation
2.If the mounting brackets are not already installed, position a
mounting bracket over the mounting holes on one side of the
unit, as shown in Figure 2.
3.Insert the screws and fully tighten using a suitable screwdriver.
4.Repeat steps 2 and 3 for the other side of the unit.
5.Using at least two people, lift the unit and slide it into the rack.
6.Secure the UPS by screwing the mounting angles to the rack face
(screws not provided). The unit is now secured in the rack.

NOTE
Installing the UPS
Follow these steps to install your UPS. Figure 3 shows a typical
installation; installing your specific model may vary. Appendix C
shows the rear panel of each model.
Some units may not recognize 50 Hz outlets. If you connect your UPS to a
start, press the ON button for 3 seconds to start the UPS on battery. Then configure the UPS input voltage
for either 100 V or 110 V (see Section 3, Configuration). The UPS recognizes the input line and goes off
battery.
DO NOT plug laser printers into a UPS. The high surge currents they produce can disrupt any manufacturer’s
UPS.
If your UPS output receptacles are divided into Load Segments, and you plan to take advantage of this
feature (available only with specific power management software), read the appropriate sections of
your power management software manual before you install the UPS.
Changes or modifications not expressly approved by the party responsible for compliance could void your
authority to operate the equipment.

SECTION 3
CONFIGURATION
This section explains:
Why you may want to change factory defaults
How to reconfigure func tions
Why Change Factory Defaults?
Input Nominal Voltage (LEDs 1, 2, 3, and 10)
If your AC input consistently fluctuates higher OR lower than the
factory-set nominal input voltage (higher than +20% OR lower than 30% of 120 V or 230 V nominal), your UPS maintains the selected
nominal input voltage by repeatedly switching to battery power. If this
creates a nuisance, you can configure the UPS nominal input voltage to
more closely match the nominal voltage of your AC input source.
Extended Nominal Voltage Range (LED 4)
If your AC input consistently fluctuates higher AND lower than the
factory-set nominal input voltage (higher than +20% AND lower than 30% of 120 V or 230 V nominal), your UPS maintains the selected
nominal input voltage by repeatedly switching to battery power. If this
creates a nuisance, you can configure the UPS nominal input voltage to
more closely match the wider range of your AC input source.
Other Settings
Reconfigure LEDs 5, 6, or 8 to change the alarms. Reconfigure LED 7 to
change the delay before unconditional shutdown. Reconfigure LED 9
so the UPS does not shut off power to the load when the UPS is on
battery power and the load is not drawing current. LEDs 11 through 14
are inactive and cannot be selected .

How to install the Remote Emergency Power Off
Communication Port Configurations
To establish communication between the UPS and a computer, plug
the UPS/Computer Interface Cable into the Comm Port. Use only the
factory-supplied cable and software. The UPS operates normally if you
do not use this port.
To prevent damage to your equipment, connect only a factory-supplied cable or a cable built to factory
specifications (see Table 4) to your RS-232 port. A standard serial cable may damage your computer.
As shown in Table 4, the communication port Pins 1 and 2 operate in
two modes. The first is Basic Alarms mode, which has AC fail alarm
and output shutdown. The second is Serial Data mode, which is UPS
Code II compliant.
The system always starts in Basic Alarms mode. When serial data is
received at Pin 1, the function of Pin 1 and Pin 2 changes to Serial Data
mode.
If serial data has not been received before going to battery power,
serial communications is disabled until AC input returns.

If the computer is running power management software, the interface

cable between the UPS and the computer’s Comm Port enables a data
exchange. Every 30 seconds, the software polls the UPS for detailed
information on the status of the power environment. If a power
emergency occurs, the software initiates the saving of all data and an
orderly shutdown of the equipment.

Option Slot
WARNING
NOTE
The option slot accepts various installable option modules that help
your UPS communicate in a variety of networking environments. See
the manual that accompanies each module for more information, or
contact your sales representative.
Load Segments
Load Segments are sets of receptacles that can be turned on
individually using our power management software. For example,
during a power outage, you can keep key pieces of equipment running
while you turn off other equipment. This feature allows you to save
battery power. See your power management software manual for
details.
Remote Emergency Power Off (REPO)
The UPS has a REPO connector that can be wired to a device that can
be used to turn the UPS off from a remote location. The following
instructions explain how to wire the REPO switch.
Connect the REPO port to dry, isolated, normally-open contacts rated 60 VDC maximum, 30 VAC RMS
maximum, 20 mA maximum. Failure to conform to these guidelines may create dangerous conditions for
the operator by disabling the safety insulation of the equipment.
Activation takes place upon closing.
1.Remove the REPO connector from the REPO port on the rear
panel of the UPS.
2.Connect dry, isolated, normally-open contacts across the REPO
device to PIN 1 and PIN 2. (Figure 8 shows the location of the
pins on the UPS REPO connector.) Use stranded non-shielded
wiring, size #22 through #18.
3.Reconnect the REPO connector to the UPS.
