When you are reading this, we believe that you have completed the connection according to the requirements of chapter
5, if you has been running your inverter , and you want to use the limiter function, please turn off AC and DC switch of the
inverter, and wait for 5 minutes until the inverter completely discharged.In order to make it easier for you to use the
limiter function, we have specifically given the wiring diagram, as shown in Picture 7.2, the yellow/green/red live line
(L1,L2,L3) connected to the utility grid live line (U/V/W), blue line means the neutral line.
We recommend installing an AC switch between the inverter outlet and the utility grid, the specs of the AC switchis
determined by the load capacity. The AC switch we recommend to connect to the inverter output refer to Table 5.2.
The SUN limiter will measure the voltage and current of three phases separately, and this manual only introduces
the installation steps of one phase, the other two phases are the same. The specific installation steps are as follows:
1) Connect SUN limiter to the grid. Connected to the grid is to measure the voltage of grid. Before connect to the grid,
please turn off the switch to avoid the risk of electric shock. Choose one wire from the bottom of the three-phase DC
switch. (any phase of U,V,W) to connect with L1 terminal, then tighten the line with a screwdriver.
2) Connect SUN limiter to clamp senor. Clamp senor can measure the current of the AC side, it should be connected
to the front side of the load (domestic appliance ect.) to achieve this function. Only when the SUN limiter collects the
voltage and current of the same phase can it judge the power of the phase. So the clamp senor should be connected
to the same phase as the before. Open the side buckle of the clamp senor, then clamp the senor to the AC line on the DC
switch, the arrow direction on the senor should towards that of the load. The clamp senor has two lines (shown as below),
and the white line corresponds to K terminal, black line corresponds to L terminal. Connect the white line to the L1(L)
and L1(K) terminal refer to the line mark of the SUN limiter and tighten the line with screwdriver. This is the whole
installation process of one phase.
