Lift up the inverter with both hands, hang the back rail on the fixed wall bracket carefully. Figure 6 Fix the wall bracket Figure 7 Mounting the inverter DC Connector Assembly Procedure Use a 2.5-4mm² PV cable, strip off the cable sheath for 7mm, insert the stripped head into the metal terminal and use a crimping plier to press it tight, insert the metal terminal into the corresponding PV connector and tighten the nut. + 2.5-4.0mm² Length:7mm _ Figure 8 Strip off the cable sheath Figure 9 Press the metal terminal Figure 10 Tighten the DC connector DC Connector Connection Ground Terminal Connection Figure 11 DC connector connection Insert the positive and negative connectors into the inverter PV connectors respectively. Note:1. Disconnect the AC breaker on the grid side when connecting the PV connectors. 2. The DC switch must be switched to "OFF" position. Figure 12 Ground terminal connection Note:Inverter must be well-grounded for resisting surge voltage shock and improving EMI performance. AC Connector Assembly Insert the stripped end of L/N/PE cable Strip off the AC cable sheath for 50mm, into the AC terminal head. Tighten the and strip off the end of L/N/PE each screws in the terminal with an Allen-key cable for 8mm. to ensure a reliable connection.
