e) Separate the DC connector as two parts: the plug and the cable nut.
f) Then tighten the cable nut.
g) Use a multimeter to measure the open circuit voltage of the positive pole
and negative pole of the PV cable, and make sure the open circuit voltage
＜600 V (Otherwise the machine may be damaged);
h) Remove the blue protective cover of the PV +&- interface at the bottom of
the inverter, and insert the completed PV terminals according to the positive
and negative correspondence.
I) Cover the remaining unused PV terminals with the original blue cover.
NOTE: Keep the DC switch of the inverter off during connection.
