To verify proper power optimizer connection:
Measure the voltage of each string individually before connecting it to the other
strings or to the inverter. Verify correct polarity by measuring the string polarity
with a voltmeter. Use a voltmeter with at least 0.1V measurement accuracy.
NOTE
Since the inverter is not yet operating, you may measure the string voltage
and verify correct polarity on the DC wires inside the Safety Switch.
For troubleshooting power optimizer operation problems, refer to Power Optimizer
Troubleshooting on page 64.
