4.4.3 DC side wiring
CAUTION!
Caution, risk of danger
The positive and negative of the battery shall not be connected in
reverse. A multimeter shall be used to determine the polarity
first, and then connect into the corresponding input ends of the
inverter.
Figure 4-4-2-3. Raise the detents
Procedure 3:
Raise the detents, and then close the doors. The schema is shown in
Figure 4-4-2-3.
Specific procedures are as follows:
1) Cut off the distribution circuit breaker at the DC side, and ensure that no voltage
on the wire at DC side.
2) Determine the positive and negative with a multimeter.
3) Connect the positive of the battery to the "DC
＋"
of DC input
4) Connect the negative of the battery to the "DC
－"
of DC input
5) Please be sure that all wirings are fastened.

4.4.4 AC side wiring
CAUTION!
Caution, risk of danger
When connecting the AC grid, cut off the circuit breaker at the
AC side to ensure that the AC wire connecting to terminals has
no electricity.
Connect AC grid:
1) Cut off the circuit breaker at AC side, to ensure that the AC wire connecting to
terminals has no electricity. Confirm it with a multimeter.
2) Connect "A" of AC output with "L1" of the grid.
3) Connect "B" of AC output with "L2" of the grid.
4) Connect "C" of AC output with "L3" of the grid.
Ensure that the wiring phase sequence at AC side is in consistent with the phase
sequence at grid side.
5) Please confirm that the wiring is fastened.
