When there is only one inverter in the PV system, connect the external grounding cable to a
nearby grounding point.
When there are multiple inverters in the PV system, connect grounding points of all inverters
and the PV array frames to the equipotential cable (according to the onsite conditions) to im-
plement an equipotential connection.
5.5.2 Connection Procedure
step 1 Prepare the cable and OT / DT terminal, refer to " Crimp OT / DT terminal " .
step 2 Remove the screw on the grounding terminal and fasten the cable with a screwdriver.
step 3 Apply paint to the grounding terminal to ensure corrosion resistance.
The grounding screws have been anchored to the side of the inverter before deliv-
ery, and do not need to be prepared.
There are two grounding terminals. Use one of them to ground the inverter.
