Introduction
Welcome!
Congratulations for your purchase of a SymmetraTM Power Array! The SymmetraTM is a UPS system with
redundant and modular power, battery and intelligence components. It is the finest protection available to
safeguard a datacenter and important data against the unpredictability of power fluctuation and failure.
Models
SymmetraTM systems can be ordered in a variety of configurations. All of these are built around one of the
frames listed below. Refer to the packaging list or the frame name plate to determine the frame model.
The internal architecture of the SymmetraTM system is comprised of a control and interface system (intelligence
modules and several user interface options) that monitors and controls a power processing system (power
modules) and a battery source (battery modules). The relationship between these functional components is
illustrated below.
Page 6 - Introduction
990-7163-001
Glossary of SymmetraTM Terms
Extended Run Battery Frame - An accessory that increases the battery capacity of a system. Multiple
Extended Run frames can be connected to a single SymmetraTM to significantly increase run time.
Hot-Swappable - Modules are “hot-swappable” when they can be replaced safely while the load equipment is
still powered and the Symmetra
TM
is fully functional.
N+1 - Refers to the level of power module redundancy. “N” represents the number of power modules required
to power the load, and “+1, +2, etc.” represents the number of extra power modules that are installed. For
example, a 7.3 kVA load requires two power modules for adequate protection. If the Symmetra
TM
is configured
with only two modules, it has an “N+0” level of redundancy, or no redundancy. If the system is configured with
three power modules, it has an “N+1” redundancy. Depending on the the load requirements, SymmetraTM can
be configured with 2, 3 or even 4 extra power modules, giving it an N+2, N+3, or N+4 level of redundancy.
Redundancy - Refers specifically to power modules. If at least one “extra” power module is installed, the
system can sustain a fault condition and still provide protection to the load equipment. To be fully redundant,
the system should be configured with at least one redundant power module, and a minimum of two battery
modules. (When two or more battery modules are present, one of them can fail and the system will still have a
battery power source. The total number of battery modules determines the length of on-battery run time.)
Scalability - The modular architecture allows the user to increase power capacity as load requirements increase. Scalability is limited by the size of the frame, and the number of available power module bays.

system can deliver. System capacity is
limited by the lesser of the frame size, or the capacity of the installed power modules.
n A Mini Frame (8kVA) with one power module installed (4kVA) has a system capacity of 4kVA.
n A Master Frame (16kVA) with five power modules (20kVA) has a system capacity of 16kVA.

Short-Term Battery Module Storage Requirements
Battery modules must be temporarily stored until the electrical wiring is connected and the SymmetraTM is
ready to be powered.
n Batteries should be stored at 0°F to 77°F (-18°C to 25°C) to preserve battery life.
n Storage environment can be within 0 to 100% relative humidity , non-condensing.
Note: Condensation will cause corrosion of electronic and chassis parts.
Caution!
n Installing battery modules in a SymmetraTM that is not powered will discharge the batteries and could
damage them permanently. Do not install battery modules into the SymmetraTM frame until after the
electrical wiring connections have been made, and the system is ready to be powered.
The SymmetraTM Power Array can be connected to either a dry contact or 24Vdc Emergency Power Off switch.
The terminal connections for the EPO switch are physically isolated from the primary circuitry of the Power
Array system.
EPO Specifications
The EPO circuit is considered a Class 2 and SELV circuit.
SELV is an acronym for “Safety Extra Low Voltage.” SELV is a common term in Europe and IEC standards. A
SELV circuit is isolated from primary circuitry through an isolating transformer and designed so that under
normal conditions, the voltage is limited to 42.4 Vpeak or 60 Vdc.
A Class 2 Circuit is a common term in North America and in UL and CSA standards. It is defined in the
Canadian Electrical Code (C22.1, Section 16) and in the National Electrical Code (NFPA 70, Article 725).
SELV and Class 2 circuits must be isolated from all primary circuitry. Do not connect any circuit to the EPO
terminal block unless it can be confirmed that the circuit is SELV or Class 2. If there is a question, use a contact
closure switch. Use one of the following cable types to connect the Symmetra
CL2 - Class 2 cable for general purpose use.
CL2P - Plenum cable for use in ducts, plenums, and other space used for environmental air.
CL2R - Riser cable for use in a vertical run in a shaft or from floor to floor.
CL2X - Limited Use cable for use in dwellings and for use in raceway.
For installation in Canada, the cable should be CSA Certified, type ELC (Extra-Low-Voltage Control Cable).

System Startup Procedure
Notice!
n Refer to Appendix A for information about the PowerView Interface.
n At least one power module, one battery module, and the main intelligence module must be installed
before the system will start.
n Load equipment can be left connected during this start-up procedure, but it should be switched off
until startup is complete.
n The PowerView can be configured to display French, Italian, German or Spanish. (Appendix A, page 3.)
1. Apply input power to the system from the utility power source.
2. Switch the input circuit breaker(s) and the system enable switch on.
3. Wait approximately 15 seconds to allow the system intelligence module to boot up and complete a startup
sequence.
4. Open the top-level menu screen on the PowerView display. (See Appendix A, page 4.)
Note: The PowerView may display some “configuration change” messages because the system was configured at
the factory with a different number of power or battery modules than are now installed. Disregard these messages,
and press the escape key to close them.
5. Verify that all power, battery and intelligence modules are detected by the system and are functioning properly by reviewing all status screens on the PowerView. (From the Status menu, open status screens for battery,
power, main intelligence, and redundant intelligence modules. See Appendix A, page 5.)
Note: If a problem is reported, ensure the system component in question is properly installed. If the problem
persists, refer to the troubleshooting information in Appendix B.

Configuration and
Advanced Operation
Notice!
n The following information should be considered when configuring the Symmetra Power Array to pro-
vide optimal power protection for your specific requirements. For detailed settings and programming
sequences, refer to The PowerView Interface - Appendix A.
Configuration
Display Settings
n The PowerView display date/time should be set to ensure an accurate set of records in the event log. The
beeper volume and screen contrast can be adjusted to meet your particular site needs.
n A password can be used to prevent unauthorized access to configuration settings. Once a password is in-
voked, changes can be made only after entering the password.
n The Startup Screen can be customized to display information that is most important to you.
System Settings (Setup)
n Shutdown and return parameters can be set to best fit your specific power environment. Consider the time
required to gracefully shut down your equipment in the event that a power outage drains the SymmetraTM to
battery exhaustion. Also consider how and when power to the load equipment should be restored after the
utility power returns.
n Output frequency can be controlled. Full Range Tracking (default) offers the widest available range. If your
equipment requires tighter limits, consider the output frequency tolerance setting and bypass control.
n Alarm thresholds can be set to protect your selected system limits. The Symmetra will constantly self moni-
tor load output and alert you with an audible alarm and an error message displayed on the PowerView screen
if a violation occurs.
n Other settings include system self test scheduling, UPS Identification setting, output voltage, and output
voltage reporting.
Logging Control
n A log of the last 64 system events is recorded and stored in the PowerView. The log function can be configured
to record only those events important to you. The event log is especially valuable for diagnosing configuration problems.
990-7168-001
Configuration and Advanced Operation - Page 1
Advanced Operation
Control Functions
Symmetra requires you to use the “power load on/off” function to deliver power to the load equipment. Other
control functions allow you to conduct a system self test, test/control external communications by simulating a
power failure, and command the system to go into and out of bypass mode. These functions are primarily used
during configuration changes or system maintainance.
Diagnostic Information
Symmetra constantly monitors itself for internal problems. If an error is detected, the display fault indicator will
light, and an error message will appear on the PowerView screen. Use this diagnostic information to determine
the source of the fault.
Status Review
The status of each modular component in the system - battery, power, and intelligence modules - can be individually reviewed using the PowerView. System settings can also be reviewed.
Load/Capacity changes
Over time, it is possible there will be an increased power demand placed on the Symmetra. As the power demand
increases, system capacity is decreased. Symmetra monitors this relationship and will initiate an audible alarm if
the user-defined parameters are violated. This can be rectified by the following methods:
a.) Increase system capacity by adding Power and Battery Modules.
b.) Change alarm settings to eliminate the violation.
c.) Reduce the load by disconnecting equipment.
Note: System capacity is limited by the lesser of the frame size, or the total capacity of the installed power modules.
Runtime Calibration
To ensure the Symmetra is accurately reporting the battery runtime. A Runtime Calibration test should be conducted at least once a year. The runtime calibration exercises the battery system to 50% discharge, and helps
maintain optimal battery function.
Accessories
The PowerView will communicate with SmartSlot accessories only when an auxilary power cable connects the
PowerView to the computer interface port at the rear of the Symmetra. Contact APC Technical Support for
information about this function.

The PowerView Interface
It is easy to use the PowerView to command, monitor and configure the SymmetraTM Power Array system. The
interface is so intuitive that even first-time users get up to speed quickly.
Notice!
n The PowerView default language is English. It can be configured to display French, Italian, German or
Spanish. See page 3.
n The PowerView can be connected or disconnected without interrupting the UPS function of the
To change the PowerView display language, an internal EPROM chip must be replaced.
Caution!
n The internal circuitry of the PowerView and the language EPROM chip are sensitive to static electricity.
Use all necessary precautions to eliminate static electricity from yourself and all tools before replacing
the chip. Do not remove the chip from the protective case until ready to install it in the PowerView.
n The PowerView cable must be disconnected from the PowerView before proceeding.
Language Chip Replacement Procedure
1. Remove four screws to separate the rear cover from the PowerView.
2. Locate the language EPROM chip. It is adjacent to a larger 40-pin chip. There is a semicircular notch at one end
of the language chip. The replacement chip must be oriented so that the semicircular notch is in the same position.
3. Insert a small flathead screwdriver between the language chip and the socket. Gently twist the blade to lift the
chip. Proceed with caution and patience to avoid bent pins.
4. Position the replacement language chip on the socket with the semicircular notch in the same orientation as
the original. Carefully ensure that all pins are properly aligned with the socket. Apply even pressure with fingers
to the top of the EPROM until it is fully seated in the socket. Replace the rear cover.

Troubleshooting
The PowerView reports various messages on the display, including alarm status and changes in system configuration. This section lists all PowerView display messages, what each means, and an appropriate corrective action.
Note: More than one of these messages may occur at one time. If this happens, be sure to review all of the messages for
a better understanding of the system condition.
The battery and power modules and the main intelligence and redundant intelligence modules are user replaceable. If a power or main intelligence module fails and a “redundant” module is present, the failed module can be
replaced without interrupting power to the load equipment.
Note: A redundant intelligence module can be replaced without interrupting power to the load, provided a functioning MIM is installed. A battery module can be replaced without interrupting power to the load, provided the Power
Array is not in the on-battery operating mode.
Module Failure Alarm Indicators
In the event of a module failure, the PowerView will display one of the following module failure messages, and the
red Fault LED status indicator will glow. The PowerView audible alarm, a pager notification, and/or software
notification may also be initiated.
The power and battery module failure messages identify the bay where the module is installed. Bay locations (L1,
L2, etc. or R2, R3, etc.) are printed on the center spine of the frame, between the module bays.
