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 SymmetraTM 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 SymmetraTM 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.

SmartSlotTM Accessories - SmartSlotTM bays at the rear of the frame accommodate up to four accessory cards. Before installing any SmartSlotTM accessory, ensure it is a compatible “SymmetraTM OK” model.

νShare-UPSTM - Provides automatic shutdown of up to two additional servers.

νPowerNetTM SNMP - Provides network UPS management.

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

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

System Capacity - The maximum output power that a SymmetraTM system can deliver. System capacity is limited by the lesser of the frame size, or the capacity of the installed power modules.

νA Mini Frame (8kVA) with one power module installed (4kVA) has a system capacity of 4kVA.

νA Master Frame (16kVA) with five power modules (20kVA) has a system capacity of 16kVA.

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 SymmetraTM to the REPO switch:

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).

Receiving and Unpacking

Receiving the SymmetraTM

The SymmetraTM Power Array frame and modular components are shipped on a number of pallets, dependant on the configuration ordered. Verify that labeled boxes match the purchase order. Consider the system component shipping weights and dimensions before moving them. If power modules are missing, check the frame. The power modules may have been pre-installed at the factory.

Inspect Packaging

Inspect packaging for signs of mishandling. If damage is detected:

1.Note the damage on the Bill of Lading.

2.File a damage claim with the shipping agent within 24 hours.

3.Notify APC of the damage claim, and condition of the equipment.
