Connected wire
Select the inner diameter of 12AWG (4mm
2
) and the outer
diameter of
Ø
5~8mm of the photovoltaic cable as the connecting line
of the PV input terminal. Select the inner diameter of
5AWG-4AWG (16mm
2
-25mm
2
) and the outer diameter of
Ø
22~28mm of the photovoltaic cable as the connecting line of the
AC output terminal. Cables should avoid high temperature, flame
and rain water whenever possible. The inverter should be
connected with earth permanently. The protective earthing
conductor cross-sectional area is more than 10mm
2
.

Tools
The multimeter, wire stripper and screw driver are required during
electric connection.
8.3.2 Wire for alternating current connection
﹡
The breaker of alternating current is cut off when wiring to assure
that there is no electricity at the terminal of alternating current
wire. And then, confirm it after measuring of multimeter.
﹡
Connect the “L1” of alternating current output with “L1” of grid;
﹡
Connect the “L2” of alternating current output with “L2” of grid;
﹡
Connect the “L3” of alternating current output with “L3” of grid;
﹡
Connect the “N” of alternating current output with “N” of grid;
(3PH, without “N”)
﹡
The earth terminal is connected with the land via guide line.
﹡
Confirm that the wiring is firm.
Warning!
Assure there is no live part of KSG-32K inverter during
electric wiring.
