θ6. Using the PowerView display, read and record the re- ported input voltage from the startup screen. (“122Vin” in figure 4-16 indicates that the input voltage is 122V.) 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.

θ7. Compare the RMS input voltage measurement (Step #2) with the input voltage as reported by the PowerView. If the reported input voltage is not within +/-5% of the recorded input voltage, check the wiring, and measure the input voltage again. If the two measurements are still outside of the acceptable range, contact APC SymmetraTM technical support at 1-888-809-TECH.

θ8. Switch the maintenance bypass switch to the “on” position. The Power Array will go into the manual by- pass mode, and voltage should now be present at the output terminal connections. The bypass LED on the PowerView display will glow, and an audible alarm may sound, and one or more messages may appear. Ignore

these messages by pressing the ESC navigation key on the PowerView display, until the startup screen reappears. See figure 4-16. Read and record the output voltage that is indicated on the PowerView. (“000Vout” in figure 4- 16 indicates that the output voltage is 000V.)

Note: The reported output voltage should be approxi- mately 208V or 240V, depending on how the system is con- figured.

θ9. Measure the output AC voltage at the output wiring terminal block connections as specified in table 4-4 be- low. Record the measured values in the table. The mea- sured values should correspond to the nominal values listed in the table. If the input voltage varies from 208V or 240V, the output voltages vary accordingly. In this case, use the multipliers in table 4-4 to calculate the ex- pected output voltages. If these voltages still vary, con- tact SymmetraTM technical support at 1-888-809-TECH.

θ10. Successful completion of steps 1 through 9 indicate that 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 can be checked and verified at this time.

θ11. 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.
