q 6. Using the PowerView display, read and record the re-
ported input voltage from the startup screen. (220Vin
in figure 4-11 indicates that the input voltage is 220V.)
Note: The PowerView may display one or more messages
such as Number of Battery Modules Changed. Press the
ESC key until the startup screen appears.

input voltage here: ______________________________

q 7. Compare the RMS input voltage measurement (Step
#2) with the input voltage as reported by the PowerView.
If the two measurements are significantly different, con-
tact APC Symmetra

q 8. Switch the maintenance bypass switch to the on po-
sition. The Power Array will go into the manual bypass
mode, and voltage should now be present at the output
terminal connections. The bypass LED on the
PowerView display will glow and one or more messages
may appear on the PowerView display. Ignore these mes-
sages by pressing the ESC navigation key on the
PowerView display until the startup screen reappears. See
figure 4-11. Read and record the output voltage that is
indicated on the PowerView. (000Vout in figure 4-11
indicates that the output voltage is 000V.)
Note: The reported output voltage should be approximately
220V, 230V, or 240V, depending on how the system is con-
figured.

output voltage here: _____________________________
q 9. Measure the output AC voltage at the output wiring
terminal block. If the measured output voltage varies
significantly from the actual input voltage, or from the
output voltage reported by the PowerView, contact

technical support.
q 10. Successful completion of steps 1 through 9 indicates
the Power Array is correctly wired to the utility power
source and that the correct output voltage is available at
the output terminal block. Load equipment voltage re-
quirements and external wiring voltages should be
checked and verified at this time.
q 11. Shut down the Power Array by switching the input
circuit breaker and the system enable switch to the off
position. Replace all wiring access panels on the Power
Array frame. The electrical connections have now been
properly installed and checked. The Power Array is now
ready for the setup procedure in Chapter 5.
