Introduction
The APC SymmetraTM Power Array is a
scalable, redundant power protection sys-
tem for multiple servers and business
critical applications. This is an introduction
to the SymmetraTM Power Array.
Thank You!
Theory of Operation
Thank you for investing in the SymmetraTM Power Array. Please
read this User's Manual thoroughly prior to installing the sys-
tem. It provides important information about installing and
using the SymmetraTM safely and effectively.
SymmetraTM Overview
The SymmetraTM is a high-performance, uninterruptible
power “array” system, designed for large-scale loads. It provides conditioned, reliable AC power to load equipment, and
provides protection from power blackouts, brownouts, swells,
sags, surges and interference. The SymmetraTM Power Array
system is comprised of either a MiniFrame, or a MasterFrame,
and a variable set of modules. A MiniFrame system can be
configured to deliver a maximum output of 8kVA, and a
MasterFrame system, a maximum of 16kVA.
The SymmetraTM Power Array is comprised of three functional components: A power processing system, a battery
source, and a control/user interface system. Output power is
routed through a transformer prior to delivery to the load
equipment. See figure I-2. Each of the functional components
and the transformer are described in the following text.
Fig I-1 MiniFrame and MasterFrame
Fig I-2 Functional Diagram of a Symmetra
TM
i
Power Processing System
Control/User Interface
The power processing system delivers conditioned AC output
power with a low distortion sinewave. Under normal operating conditions, power is received from the AC utility power
source, conditioned by the power processing system, and delivered to the load equipment. In the event of an AC utility
source failure, the power processing system receives power
from the battery source (battery modules), converts it to conditioned AC, and delivers it to the load equipment. When AC
utility power is present, the power processing system also
maintains the battery source at full charge.
The power processing system in SymmetraTM is comprised of
individual power module(s). Each power module contains
the electronics for a complete 4kVA UPS, including the rectifier,
charger and inverter. When two or more power modules are
present, they operate in parallel, sharing the load equally.
By configuring the system with at least one more power module than is required to power the load (a redundant power
module), SymmetraTM can sustain a power module failure,
and still deliver full power to the load equipment. The failed
module is identified by the control/user interface system, an
alarm is initiated to notify the user of the module failure, and
the hot-swappable module can be replaced by the user, without the need to power down the load equipment.
A SymmetraTM MiniFrame provides bays for up to three power
modules, and a MasterFrame provides bays for up to five.
This provides the full system capacity (8kVA and 16kVA respectively), plus one redundant power module.
Battery Source
The control/user interface system coordinates the operation
of the SymmetraTM and reports status conditions via several
user interface options. Functions performed by the control/
user interface component include module coordination and
state control, analysis and reporting of system status, and
reporting of alarm conditions.
Module Coordination & State Control - The Symmetra
incorporates a main intelligence module (MIM) that continuously monitors the system, and delivers data to both the
PowerView user interface, and to the communication ports.
The MIM coordinates the initial power up of the system, transfers it into and out of bypass mode, transfers the power source
between the utility AC power, and the battery source, and coordinates shutdown operations.
System Status Monitoring - The MIM gathers data about the
system components, and delivers it to both the PowerView
interface, and to the computer interface ports. System status
monitoring and reporting data include the current predicted
run time, the status of individual battery modules and power
modules, input & output voltage, input & output voltage frequency, and the size and status of the current output load.
Alarm Condition Detection - The control/user interface system monitors the SymmetraTM for alarm conditions. If an
alarm condition is detected, the PowerView user interface initiates an audible and visual alarm. Alarm conditions include
on-battery, low battery, module faults, overloads, loss of redundancy and a variety of other default and user defined events.
All possible alarm messages and the appropriate user responses
are provided in chapter 10.
TM
The battery source is comprised of parallel, hot-swappable,
120V battery modules. These are housed in the Symmetra
frame, and in an optional extension battery frame.
A SymmetraTM MiniFrame provides bays for up to two battery modules, and a MasterFrame provides bays for up to
four. Both of these frames can be connected to an extension
battery frame. Additional battery modules increase on-battery run time.
ii
TM
Transformer
The power processing system receives either 208V or 240V
input AC utility power, and delivers 240V power to an internal
transformer. The transformer delivers multiple output voltages (120V/208V/240V) to an output wiring terminal block
inside the SymmetraTM frame. Output wiring procedures are
provided in chapter 4.
Modes of Operation
The Power Array functions in one of four modes of operation,
depending on user commands, the status of the AC utility
voltage, and the condition of the SymmetraTM itself. The four
modes are Load-Disconnect, On-Line, On-Battery, and Bypass. The PowerView interface reports the operating mode.
Load-Disconnect Mode
In the load-disconnect mode, incoming AC utility power is
present and the system is internally powered, but no output
power is delivered to the load equipment. The Symmetra
enters the load-disconnect mode at the initial power up, when
the system enable switch is switched to the “on” position. When
the system is operating on-line, and the “load off ” command
is entered in the PowerView interface, it returns to the loaddisconnect mode. Figure I-3 illustrates the power flow when
the system is operating in the load-disconnect mode.
TM
On-Line Operating Mode
The on-line operating mode is the “normal” operating mode.
When the system is in the on-line operating mode, the Power
Array receives power from the AC utility, and delivers conditioned power to the load equipment. The Power Array maintains proper battery charge, regulates the output voltage and
frequency, and protects the load from surges and electrical
noise. SymmetraTM will operate in this mode if it has been
commanded to turn the load on, the incoming utility voltage
is present and functioning properly, and there are no preventing abnormal conditions, such as an overload. See figure I-4
for a diagram of the power flow when the system is in the online operating mode.
Fig I-3 Load-Disconnect Operating Mode
Fig I-4 On-Line Operating Mode
iii
On-Battery Operating Mode
Bypass Operating Mode
When in the on-battery mode, the Power Array draws DC
power from the battery source, converts it to conditioned AC
power that is then delivered to the load equipment.
SymmetraTM typically enters this mode in the event of a utility
power failure. It will also operate in the on-battery mode
during a user initiated battery self test.
On-battery operation is limited in duration and is dependent
upon the number of battery modules, their state of charge,
and the size of the load. SymmetraTM will remain in the onbattery state until either the incoming utility power is restored,
or the batteries are depleted. See figure I-5 for a diagram of the
power flow when the system is in the on-battery mode.
When the SymmetraTM is in the bypass operating mode, the
system is bypassed, and utility power is delivered directly to
the load. SymmetraTM is equipped with an automatic bypass
function to allow the system to automatically go into bypass
mode, and a manual maintenance bypass switch to allow a
user to manually bypass the system. Either can be used to
place the Power Array into bypass operating mode.
The SymmetraTM will automatically transfer to the bypass
operating mode when AC utility power is present, but the load
cannot be powered by the inverter. Events which may cause
this include overloads, or failed non-redundant power modules. The SymmetraTM will automatically return to the on-line
mode when the triggering event clears. Figure I-6 illustrates
the power flow when the system is in the bypass mode.
Fig I-5 On-Battery Operating Mode
Fig I-6 Bypass Operating Mode

Definitions
Important Information
The following definitions are used in this manual and will be
helpful in understanding SymmetraTM.
Redundancy - Indicates the presence of one or more extra
modules, allowing the system to sustain a fault and continue
to provide full protection to the load. To be fully redundant,
the system should be configured with a redundant intelligence
module, and at least one redundant power module.
Note: The number of battery modules determines the length of
the run time. While it is prudent to use the maximum number
of battery modules possible, they are not considered redundant.
N+1 Redundancy - Refers to the level of redundancy, specifically related to power modules. “N” represents the number of
modules required to power the load, and “+1, +2, etc.” represents the number of extra power modules that are present.
For example, a 7.3 kVA load requires two power modules for
adequate protection. If the SymmetraTM is configured with
only two modules, it has an “N+0,” level of redundancy. (No
redundancy). If the system is configured with three power
modules, it has an “N+1” redundancy. Depending on the size
of the load, SymmetraTM can be configured with 2, 3 or even 4
extra power modules. Respectively, it would have an N+2,
N+3, or N+4 level of redundancy.
Please read this User's Manual thoroughly, before proceeding
with the installation of the SymmetraTM Power Array system.
It provides important information about installing and using
the SymmetraTM safely and effectively. Pay close attention to
text that is accompanied by a danger, or caution symbol. For
technical support, contact APC at:
1-888-809-TECH
Capacity - The maximum amount of output power that a
SymmetraTM system can deliver. The capacity is limited by the
lesser of the frame size, or the capacity of the installed power
modules.
For example, a MiniFrame (8kVA) with one power module
installed (4kVA) has a system capacity of 4kVA. A MasterFrame
(16kVA) with five power modules (20kVA) has a system capacity of 16kVA.
Hot-swappable - The modules are “hot-swappable” means
they can be replaced safely by a user or service provider while
the load is still powered and fully protected.

Safety Information
Important Safety Information
Read this safety information in its entirety,
before proceeding with the installation &
operation of the SymmetraTM Power Array.
Safety
Symbols Used In This Manual
The following symbols appear in this User's Manual:
CAUTION/DANGER - Caution indicates risk of
bodily harm. Danger indicates that a risk of electrical shock is present and the associated procedures should be followed carefully.
“STAND BY MODE” - The system enable switch,
and the input circuit breaker use the “stand by”
mode. When either of these are switched to “stand
by,” the Power Array is disconnected from utility
input voltage. In this mode, the system appears to
be off, although the utility power is still connected
to the system. For this reason, the standby mode
is unsafe for servicing the system. Always follow the
five step Total Power Off procedure before servicing the Power Array. (See procedure at right.)
“OFF POSITION” - The maintenance bypass
switch is the only switch that can be placed in the
“off” position. When switched to the “off” position, the Power Array functions normally, receiving power from the utility source, and delivering
conditioned power to the load equipment.
“ON POSITION” - All three switches (The system enable switch, the maintenance bypass switch
and the input circuit breaker) can be placed in the
“on” position. See the description for each of these
switches in chapter 1.
SAFETY EARTH GROUND - Indicates the primary safety ground.

The PowerView functions as the user interface for the MIM,
and is used to access data, and to configure the system. When
a redundant intelligence module is installed and functioning,
the main intelligence module can be replaced without placing
the load at risk. The main intelligence module also communicates to an external battery frame (if present). The main intelligence module and the redundant intelligence module are factory installed into custom racks that are built into the bay at
the upper right of the frame.
Important: The MIM is always installed in the bottom rack, and
the RIM is always installed in the top rack.
Redundant Intelligence Module
(RIM)
The redundant intelligence module is a back-up version of the
main intelligence module. It provides redundancy in the event
of a MIM failure, or while a MIM is being replaced. If a functioning MIM is present, the RIM can be removed and replaced
without placing the load at risk. The condition of the RIM can
be determined with the PowerView.
Input Circuit Breaker
The input circuit breaker protects the Power Array from extreme overloads. When switched to “stand by” the Power
Array is disconnected from incoming utility voltage. When
switched to the “on” position, power flows from the utility
source into the Power Array. Under normal operating conditions, the input circuit breaker always remains in the “on” position.
Fig 1-8 Input Circuit Breaker & Maintenance Bypass Switch
Maintenance Bypass Switch
When switched to the “on” position, the maintenance bypass
switch bypasses the Power Array, and causes the load equipment to be powered directly from utility power. When it is
switched to the “off ” position, utility power flows into the
Power Array, and conditioned power is delivered to the load
equipment. The load equipment is unprotected when the main-
tenance bypass switch is in the “on” position. Under normal
operating conditions, the maintenace bypass switch always
remains in the “off” position.

Site Preparation
This chapter provides the site requirements
for a SymmetraTM Power Array system.
Included are structural and environmental
requirements, weights, dimensions and the
heat output of a functioning system.
Chapter 2 - Site Preparation
Space and Weight Considerations
All Power Array frames are 24” wide and 27” deep. Refer to
table 4-1 for dimensions and weights of fully loaded systems.
Table 2-1 Power Array Dimensions and Weights (Fully
Loaded with Modules)
Make sure there is adequate space and structural integrity to
support the fully loaded frame. Refer to figure 2-1 below. The
weight of the Power Array rests on four 1.5” diameter leveling
feet. Positions of the leveling feet are shown. When installing
the frame, allow 12” of clearance behind the frame for adequate airflow. (The fans on the system pull air in through the
front of the frame, and blows it out the back.) Allow 48” of
clearance in the front of the SymmetraTM to access the
PowerView interface, and for installation and replacement of
modules.

Operating Conditions
The Power Array is intended for installation in a temperaturecontrolled, indoor area, free of conductive contaminants. The
operating evironment must be clean, dry and protected. The
atmosphere must be free of dust and corrosive fumes. Adequate airflow must be provided for the operation of the system. Make sure environmental conditions where the
SymmetraTM is to be installed are within the following parameters:
n Operating Relative Humidity: The Power Array will op-
erate within a relative humidity range of 0 to 95%, noncondensing.
n Operating Temperature: The Power Array will operate
within a temperature range of 32°F to 104°F (0°C to 40°C).
n Operating Elevation: The Power Array will operate at
elevations within a range of 0ft to 10,000ft (0m to 3,048m).
n Electro-Static Discharge (ESD) Susceptibility: The Power
Array and all modules are capable of withstanding
“through air” electro-static discharges up to an amplitude of +/-15kV and “direct discharge” electro-static discharges up to an amplitude of +/-8kV without failure,
abnormal operation or degradation in performance. ESD
test methods conform to IEC 801-2.

Transporting Power Array to Installation Site
When it is shipped, the Power Array frame is bolted to a custom-designed pallet. The modules are stacked on either one
or two additional pallets. It is recommended that these pallets
be moved from the receiving dock to the installation area with
a pallet jack. Make sure there is enough space and structural
integrity to move these pallets.
Refer to table 2-2 for BTU output of a fully loaded, and functioning Power Array system. The BTU output is significantly
higher while the batteries are charging. Under normal operating conditions, battery recharge periods are relatively infrequent.
Table 2-2 BTU Output
Temporary Storage of Modules
The battery and power modules must be temporarily stored
until the frame is permanently installed. To preserve battery
life, always store batteries in a cool, dry place.

Unpacking and Installing Frame
Because the installation process begins on
the loading dock, this chapter provides the
procedures for inspecting the Symmetra
Power Array frame and modular components
when they arrive. It includes procedures for
moving the frame to the installation site,
removing it from the pallet, and preparing the
frame and the modules for installation.
