Start-up Procedure
(continued)
Operational Test
1.
Switch ON the double pole 15 amp AC circuit breakers located in the ST unit. These
breakers provide the ST produced power to the utility and provides the necessary utility
voltage and frequency to the inverter (the inverter will not produce an AC output if utility
voltage is not present on its output). Refer to Figure 16, item 1.
2.
Switch ON the 100 amp DC circuit breaker located in the ST unit. This breaker supplies
the DC power from the PV array to the ST unit. Refer to Figure 16, item 2.
3.
Switch the 1 and 100 amp (ganged) PVGFP breakers to ON (if installed). These breakers
open when 1 amp or greater is detected in the DC negative to ground line; indicating a
ground fault condition. Refer to Figure 16, item 3.
4.
The inverter's Liquid Crystal Display (LCD) displays the product name, software revision,
Trace Engineering name, and finally the operational values during this sequence. During
the 5-minute timer, AC voltage, frequency, and DC voltage appear on the display (Figure
17).
