The following pages comprise the inital configuration of the
Symmetra
TM
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.

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.
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.)
