Danger
！
When the input AC terminal is connected with the inverter, the circuit br eaker at
the AC input side shall be disconnected, otherwise the AC input will generate
dangerous voltage, causing personal injury and death. Do not operate wiring by
non professionals.
Please make sure the AC input and AC output wiring is correct, Do not connect
the input and output reversely, otherwise the inverter will be damaged.
Please make sure that three phase AC input the R, S, T and grounding are
correctly connected to the Corresponding terminals. Do not connect the AC input
R, S, T to the grounding terminal wrongly. Otherwise, it will damage inverter.
6.5 DC input side electrical connection
Danger
！
When carrying out connection between PV array and inverter, the PV arra y
should be covered with opaque materials and the DC -SW ITCH should be
disconnected, otherwise, the PV array may generate dangerous voltage, cause
Note
！
The phase sequence between AC pump and inverter must be same, otherwise, it
shall lead to less output or without water. W hether Phase sequence is
corresponding or not should be tested when the pump system trial run for the first
time.
For single phase pump, there is no sequence required after start capacitors are
moved out.
