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 can deliver a maximum of 16kVA.

The power processing system delivers conditioned AC output power with a low distortion sinewave. Under normal operating conditions, power is received from the AC mains (utility) power source, conditioned by the power processing system, and delivered to the load equipment. In the event of an AC mains power 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 mains power is present, the power processing system also maintains the battery source at full charge.

The power processing system in SymmetraTM is comprised of one or more power modules. Each power module contains the electronic components 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.

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 mains 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 and power modules, the input & output voltage, input & output voltage frequency, and the size and status of the 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 9.

BatterBatter

The battery source is comprised of parallel, hot-swappable, 120V battery modules. These are housed in the Symmetra frame, and in an optional XR 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 XR Extension Battery frame. Additional battery modules increase onbattery run time.

Modes of OperationModes of Operation

Modes of Operation

Modes of OperationModes of Operation

The Power Array functions in one of four modes of operation depending on user commands, the status of the AC mains (utility) voltage, and the condition of the SymmetraTM itself. The four modes are Load-Disconnect, On-Line, On-Battery, and Bypass. The PowerView reports the operating mode.

Load-Disconnect Mode

In the load-disconnect mode, incoming mains (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 power flow when the system is operating in the load-disconnect mode.

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 AC mains (utility) power 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.

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 and delivers it to the load equipment. Symmetra

typically enters this mode in the event of a mains (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 on the number of battery modules, their state of charge, and the size of the load. SymmetraTM will remain in the on-battery state until either the incoming utility power is restored or the batteries are depleted. See figure I-5 for a diagram of 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 mains power is present, but the load cannot be powered by the inverter. Events which may cause this include overloads and failed non-redundant power modules. The SymmetraTM will automatically return to the on-line mode when the triggering event clears. Figure I-6 illustrates power flow when the system is in the bypass mode.

The following terms are used in this manual. Review these definitions for a better understanding of the SymmetraTM:

Redundancy - Indicates the presence of one or more extra power modules which allow the system to sustain a fault and still provide 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 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 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, see the inside front cover of this manual.

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.

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 mains (utility) input voltage. In this mode, the system appears to be off, although the mains (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 mains (utility) power, 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.

The MIM is the computer for the Power Array system. It gathers and processes data, including monitoring the condition of each of the modules.

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 with an external battery frame (if present). The main intelligence and the redundant intelligence module are factory installed in the upper right bay of the frame.

Important: The MIM is always installed in the bottom rack, and the RIM is always installed in the top rack in this bay.

Remote Emergency Power Off Switch

Chapter 4 - Electrical Requirements and Procedures

REPO Switch InstallationREPO Switch Installation

REPO Switch Installation

REPO Switch InstallationREPO Switch Installation

The Power Array can be de-energized with a remote emergency power off (REPO) switch. REPO switches are common in computer rooms where, for safety reasons, power to the loads must be quickly disconnected. The REPO switch physically flips the system enable switch to stand by mode. This cuts power to the main intelligence module, which in turn cuts power to the Power Array and to the load equipment. The system enable switch must be physically reset.

IMPORTANT: The system enable switch cuts power to the intelligence module only. All internal circuitry that is connected to incoming utility (mains) voltage is still powered if incoming utility power is still present.

The REPO can be connected to either a switched, 24Vdc circuit, or a simple contact closure.

REPO SpecificationsREPO Specifications

REPO Specifications

REPO SpecificationsREPO Specifications

The REPO 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.

n Verify that all incoming line voltage (mains power)

and low voltage (control) circuits are de-energized and locked out before installing cables or making connections, whether in the junction box or to the SymmetraTM Power Array.

n Always verify that all battery modules are removed

and all battery extension frames are disconnected from the Power Array before installing any wiring to the Power Array.

REPO Wiring Procedures

1. Refer to figure 4-8. Remove the screw holding the twopiece access panel at the rear of the Power Array. Remove the panel. Set the screw and the panel pieces aside.

Cable Specifications

The cable that connects SymmetraTM to the Emergency Power Off switch should be one of the following UL Listed types:

CL2 - Class 2 cable for general purpose use; or CL2P - Plenum cable for use in ducts, plenums, and other

space used for environmental air; or CL2R - Riser cable for use in a vertical run in a shaft or from

floor to floor; or CL2X - Limited Use cable for use in dwellings and for use in

raceway. For installation in Canada, the cable should be CSA Certi-

fied, type ELC (Extra-Low-Voltage Control Cable).

Fig 4-8 Removal of REPO Wiring Panels

2. Refer to figures 4-9 and 4-10. Select the configuration that matches the type of REPO switch that is to be installed.

Note: An existing jumper must be removed from the terminal block if a 24Vdc REPO switch (figure 4-10) is to be installed.

3. Extend the wiring from the switch to the Power Array. Strip 13 mm (1/2") of insulation from the end of each of the incoming wires.

4. Feed the wires through the knockout in the access panel, and install a strain relief (Romex) connector.

After the input and output wiring has been properly connected and checked by a qualified electrican, the Power Array is ready for the installation of the battery and power modules. After they are installed, the grill covers are replaced onto the frame, and the PowerView user interface is mounted onto the frame.

Frame Leveling Procedure

Position the Power Array so there will be adequate airflow clearance in the front and the rear of the frame. See figure 5-

1. The weight of the Power Array is supported by four 3.8cm (1.5") leveling feet pads. Four metal plates can be placed under each of the leveling feet pads to help displace the weight of the Power Array.

The procedure for leveling the frame is as follows:

1. Hand turn all four leveling feet until the pads make contact with the floor.

2. Use an open-end wrench to extend each of the leveling feet by turning the hex nut three complete revolutions.

3. Adjust the leveling feet until the frame is level front to back and side to side.

Fig 5-4 Battery Alignment Grooves and Runners

Note: As the battery module slides into the bay, a retaining flange

will fall behind a notch in the frame. See figure 5-5. This is a safety feature. When the battery module is removed from the frame, this flange prevents the battery from falling out of the bay until both people have assumed the full weight of the module.

Battery Module

Fig 5-3 Location of Battery Module Bays

Note: There are two alignment grooves molded into each bat-

tery module bay. These correspond with runners on the bottom of each battery module. See figure 5-4.

2. With one person on either side of the battery module, lift the module, align the runners with the alignment grooves, and slide the module into a bay. Always install power or battery modules in the lowest available bays. Installing them in this manner minimizes lifting and lowers the center of gravity of the Power Array system.

Fig 5-5 Battery Module Retaining Flange

3. Engage the internal electrical connector by swiftly and firmly pushing the battery module into place. The battery module design incorporates a drop lock that engages when the battery module is properly seated in the bay. If this lock does not engage, a slight tug will move the module. When it is locked, the battery module sits firmly in place and must be lifted slightly before it can be pulled from the bay.

Physical Features of the Powerview

The PowerView interface incorporates a 4 x 20 alphanumeric liquid crystal display (LCD), four navigation keys, four light emitting diode (LED) indicators, and an audible alarm beeper. It is designed to either mount on the front of the frame, to stand on top of the frame, or to be installed at a remote location up to 6.1m (20') away. A short RJ45 cable is hardwired to the top right module bay of the frame. This cable connects to the PowerView when it is mounted onto the frame. A 6.1m (20') RJ45 cable is provided for remote installation of the PowerView.

PowerView Functions

An overview of each of the PowerView interface functions are provided below:

n User Interface - The PowerView is used to command the

system to power up, and power down the load equipment, to review the status of modular and system components, and to configure functionality of the system.

n Alarms and Alarm Thresholds - In the event of a power

disturbance, or loss of a system component, (and other user-configured alarm conditions), the PowerView interface emits both an audible alarm and displays a visual message on the LCD screen*. Procedures for setting user configurable parameters are provided in Chapter 7. All PowerView display messages, and the corrective actions are provided in Chapter 9.

n Set System Function Parameters - The PowerView can

be used to set parameters for the functioning of the Power Array. These include acceptable input and output frequency ranges, frequency of self tests, and minimum/ maximum settings for power transfers.

Fig 6-1 The PowerView Interface

n PowerView Interface Parameters - The PowerView can

be used to set the contrast of the LCD screen, select the information that is displayed in the startup screen, set the time, date, password and the volume of the audible alarm.

n Event Logging - The 64 most recent power and user

events are recorded and logged into the PowerView interface. The interface can be configured to log a specific set or range of data. This data, as well as compiled statistics can be reviewed using the PowerView interface.

n Check Status and Diagnostics - Input voltage, output

voltage, available run time, load size, the present operating mode, and the status of every module in the Power Array frame can be reviewed using the PowerView interface. (See Chapter 7.)

n Testing - The PowerView interface can be used to per-

form a system self test and to simulate a power failure.

n Help Function - Pressing the up and down navigation

keys simultaneously launches context sensitive help.

*For example, a Power Array with an N+1 redundancy can be configured to emit an audible alarm if the system incurs the lose of a redundant power module. (Typically, this would be the result of additional load being added, or a power module failure.)

Language ConfigurationLanguage Configuration

The factory default PowerView language is English. It can be configured to display French, Italian, German or Spanish text by replacing an EPROM (erasable, programmable read only memory) chip. A set of replacement EPROM chips are included with the PowerView. Follow these steps to replace the language EPROM:

Note: The internal circuitry of the PowerView, and the EPROM 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 you are ready to install it in the PowerView.

n Before disassembling the PowerView, touch a grounded

metal object to thoroughly ground all static charge.

n The PowerView cable must be disconnected from the

PowerView before proceeding.

1. Working on a flat table or other suitable work surface, remove the four Phillips screws at the rear of the PowerView. Separate the back half from the PowerView.

2. Identify the 28-pin language EPROM chip inside the PowerView. See figure 6-4. The EPROM chip is adjacent to a larger 40-pin chip, and is labeled with the name of the language. Note the semicircular notch at one end of the EPROM. The replacement EPROM must be installed so that the semicircular notch is in the same orientation.

3. To remove the EPROM, insert a small flathead screwdriver between the EPROM and the socket. Gently twist the blade to lift the EPROM from the socket. To avoid bent pins, proceed with caution and patience. Gradually loosen the chip, one side at a time, until it is free from the socket.

4. Position the replacement EPROM on the socket with the semicircular notch in the same position as the original.

Important: Carefully check that all pins are properly aligned with the socket.

5. Apply even pressure with fingers to the top of the EPROM until it is fully seated in the socket.

6. Replace the rear cover and re-install the four Phillips screws.

: Powering the Power Array: Powering the Power Array

: Powering the Power Array

: Powering the Power Array: Powering the Power Array

The following pages comprise the inital configuration of the SymmetraTM system. Read and follow these procedures carefully. When they are completed, the Power Array system will be configured to provide optimal power protection for the data center or other load equipment.

The following procedures assume that the Power Array system is not yet powered. If the Power Array is already powered, check to make sure the load equipment is in a safe state to be switched off, and then switch the load equipment off. Switch the system enable switch and the input circuit breaker to the stand by position. Switch the maintenance bypass to the off position.

Note: Refer to chapter 1 for the location of these switches.

In this step the Power Array is powered while the load equipment remains unpowered.

1. Make sure all input, output and EPO wiring has been installed by a qualified electrican.

Important: Make sure that the electrican has completed the electrical wiring test/checklist at the end of Chapter 4. Make

sure all modules have been installed correctly, that all grill covers have been replaced onto the frame, and the PowerView has been properly connected.

2. Switch the input circuit breaker to the on position. The Power Array is now connected to the mains (utility) power source.

3. Switch the system enable switch to the on position. The startup screen will appear on the PowerView interface.

Note: When the system enable switch is switched to the on

position, the Power Array runs through a series of internal tests. Allow the Power Array to start up for a minimum of 10 seconds before entering commands into the PowerView interface.

Fig 7-1 Startup Screen

4. The first line of the startup screen displays the battery capacity.*

The second line displays the load capacity. The load capacity is 000% in this illustration because the load is not powered yet. The third line displays the input voltage (220Vin), the output voltage (000Vout), and the input voltage frequency (50Hz). Again, the output voltage in the illustration is 000Vout because the load has not been powered.

The fourth line displays the predicted battery run time for the current load. Until the load is powered, this run time will not be meaningful.

* There may be some battery discharge during handling and shipping of the Power Array. If batteries are showing less than 50% capacity, allow the batteries to charge before proceeding. (To charge battery modules, leave the system enable switch and the input circuit breaker in the on position, and allow the Power Array to remain idle for 30 minutes.)

1. Use the sequence in figure 7-2 to enter the Turn Load On command.

2. The Power Array has now been instructed to power up the load equipment. It conducts a self diagnosis and determines if the conditions are safe to deliver power to the load equipment. Depending on the diagnostics, the Power Array will either power the load or one of several startup over-ride messages will appear. A startup over-ride message indicates an exceptional condition exists and gives the option to proceed or abort. An example of a startup over-ride message is displayed below:

Each line of the shutdown parameter selection screen contains a configuration parameter. To set a parameter, select a line and press the Enter key. Note the flashing up/down arrow appears. Select the desired parameter by scrolling up or down through the choices using the Arrow navigation keys. When the desired parameter is displayed, press the Enter key. The parameter is then recorded into the PowerView memory.

Low Battery Duration - When in the on battery mode, the Power Array will signal an alarm 2, 5, 7, or 10 minutes before system shutdown will occur due to battery exhaustion. Make this selection based on the time that is required to save all data and switch off the load equipment.

Shutdown Delay - Some computer networks that issue shutdown commands require some additional run time after that command is issued to gracefully shut itself down. If your computer network is one of these, the Power Array provides a choice of a 20, 180, 300, or 600-second delay from the receipt of the shutdown command before the Power Array stops powering the load equipment.

Return Delay - when utility (mains) power is restored after a power failure, a delay interval may be desirable to allow utility power to stabilize before the system goes back on line. The return delay interval choices are 0, 60, 180, or 300 seconds.

Return Battery Capacity - When returning from an extended utility (mains) power failure, a minimum battery capacity is often desired before repowering the load. The choice of values for this paramer are 0, 10, 25, and 90%. This minimal requirement ensures there will be sufficient battery run time to safely shutdown the load in the event of a subsequent power failure. Press the Enter key to record your selection, and then press the Escape key to return to the startup screen.

Select a desired alarm parameter by scrolling up or down through the choices using the arrow navigation keys. When the desired parameter is displayed, press the Enter key. The parameter is then recorded into the PowerView memory.

Redundancy Alarm Threshold - The Power Array will signal an alarm if redundancy falls below this threshold. Base this selection on the number of power modules present (4kVA each), the size of the load, and the power module redundancy requirements. If redundant power modules are installed, it is highly recommended that this threshold be set so that the alarm will be initiated if the redundancy is lost (possibly as a result of an unauthorized increase of the load).

Maximum Load Threshold - The maximum load threshold can be set in increments of 2kVA. If the load exceeds this threshold, the alarm will sound.

Minimum Run Time Threshold - Select a minimum available run time specifically for your power requirements. In the event that the Power View predicts the available run time is less than this threshold, an alarm will sound.

Switching Audible Alarm Beeper Off

Use the following sequence to access the beeper alarm on/off command: Top level menu-Display-Beeper-Vol-select off.
