Introduction - Page 5

Basic Operation

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.

SmartSlot

cards. Before installing any SmartSlot

n Share-UPS
n PowerNet
n Measure-UPS
n Call-UPS

TM

Accessories - SmartSlotTM bays at the rear of the frame accommodate up to four accessory

TM

- Provides automatic shutdown of up to two additional servers.

TM

SNMP - Provides network UPS management.

TM

II - Provides environmental information such as ambient temperature and humidity.

TM

- Works with an external modem to provide out-of-band UPS management.

TM

accessory, ensure it is a compatible “Symmetra

TM

OK” model.

System Capacity - The maximum output power that a Symmetra

TM

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.

Electrical Requirements - EPO Switch

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
