Introduction
The following pages comprise the inital configuration of the
Symmetra
TM
system. Read and follow these steps 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 sys-
tem is not yet powered. If the Power Array is already pow-
ered, check to make sure the loads are 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 the switches.

Step 1: Powering the Power Array
In this step the Power Array is powered, while the loads re-
main unpowered.
1. Make sure all input, output and EPO wiring has been in-
stalled by a licenced electrican. Check to insure that the
electrican has completed the electrical wiring test/checklist
at the end of chapter 4. Make sure all modules and the
PowerView are installed correctly, and that all front grill cov-
ers have been replaced onto the frame.
2. Switch the input circuit breaker to the “on” position. The
Power Array is now connected to utility voltage.
3. Switch the system enable switch to the “on” position. The
startup screen will appear on the display.
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. This
displays 000% because the load is not powered yet. The third
line displays the input and output voltage, and the input fre-
quency. Again, the output voltage should read “000Vout”
because the load has not been powered. The fourth line dis-
plays the predicted run time for the current load. Until the
load is powered, this run time will not be meaningful.
* Under ideal conditions, the batteries would be at 100% ca-
pacity. Typically, there will be some battery discharge during
handling and shipping of the Power Array. If batteries are show-
ing less than 50% capacity, allow the batteries to charge before
proceeding. (Leave the system enable switch and the input cir-
cuit breaker in the “on” position.)
