Chapter 7 - Configuring & Operating the SymmetraTM
Introduction
The following pages comprise the inital configuration of the SymmetraTM system. Read and follow these procedures care- fully. 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 sys- tem is not yet powered. If the Power Array is already pow- ered, 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.
Step 1: Powering the Power Array
In this step the Power Array is powered while the load equip- ment remains unpowered.
1.Make sure all input, output and EPO wiring has been in- stalled 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.

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.)
