a). Make sure that the polarity of the output voltage of the solar panel is
consistent with the polarity identified by the inverter
b). Connect DC positive and negative to the inverter input terminal.
Figure 5.1 is shown in figure 5.2。

c).Making DC connection line Strip off the DC wire about 7mm, disassemble
the connector cap nut(see figure5.3)
2). Insert the contact pin into the connector housing until it locks in place.
Screw the cap nut onto the connector housing. Torque to 2.5-3Nm
(as shown in figure 5.5)
3).Finally insert the DC connector into the positive and negative input of the
inverter，shown as figure 5.6
1). Crimping metal terminals with crimping pliers as shown in 5.4
