7. Tighten terminal screws with 15 in-lbs (1.7N-m) of torque. Check that all
terminals and cables are secured.
3.4.3 Wiring Checklist
(1) Measure the utility power quality of each phase. Make sure the waveform of
voltage is a pure sine wave without any harmonics right after your PV system is
completed. Performing the measurement when your PV system is at maximum
power generation is recommended.
(2) If harmonics exist in your PV system, one or more of capacitors or AC filters
DANGER:
High voltages exist between terminals of PV panels when Panel is
exposed to sufficient irradiation. Exposed terminals of the PV-Panel
can cause electric shock. Avoid making physical contact with those
parts of the device.
NOTICE:
Before connecting PV-Panels to DC terminals, make sure the polarity
of each connection is correct. An incorrect connection could
permanently damage the device.
NOTICE:
Perform an AC power quality measurement after the PV system is
completed to check for any abnormal AC grid condition or harmonics.
NOTICE:
Any degradation or damage of the device due to nonperformance of
the AC grid (non-compliance with IEEE standards) or uncontrolled
power quality is out of the scope of warranty.
