Danger
！
When the input AC terminal is connected with the inverter, the circuit breaker
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.
Make sure single AC input Live line , neutral line and grounded line are
connected to corresponding R,S and PE terminals, T keeps without any
connection, Do not connect R, S and AC input grounding wrongly.
Notice
！
The phase sequence between AC pump and inverter must be same,
otherwise, it shall lead to less output or without water. Whether 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.
