This manual is for use by qualified personnel only.
12. Open the inverter assembly’s right door only.
13. Wearing appropriate personal protective equipment and using a voltmeter
with minimum ratings of 1000 volts AC and DC that has been tested on a
known AC voltage source and a known DC voltage source before use,
measure DC voltage from line to line and from line to ground (see Figure ii):
• Between the PV+ bus bar and the PV- bus bar and to ground to make
sure the inverter side of the DC switch is de-energized.
• Between the terminals of F5 and F6 and to ground to make sure the DC
input side of the DC switch is de-energized. Measure only from the top of
the F5 and F6 fuse holders. Measuring from the bottom could result in a
false reading.
Do not proceed until the voltage has decreased to 0 VDC.
NOTICE
Use the support bar for the bus bars as the ground point or any other
unpainted enclosure framework that is connected to earth ground.
