4.2.2 Main Circuit Wiring
4.2.2.1 PV Input Terminal
Install a DC switch between PV string output and PV+/PV- terminal on controller. Surge
protector controller is also suggested to install.
Connect PV input wires from string PV+/PV- to DC swtich; DC switch to PV+/PV- terminal of
controller.
Ensure the max. voltage of PV will not over 750V at any condition, or may damage the
controller.
4.2.2.2 Power Output Terminal
Connect AC controller output terminals U/T1, V/T2 and W/T3 to loadinput terminals U, V and
W respectively. Ensure the loadand controller terminals are in same phase sequence or the
loadwill rotate reversely.
