please make sure that the connection is tight, otherwise, it may overhea t,
and lead to burn the connector.

Step3:
Connect the cables between pumping inverter and AC pump .
6.5 DC Side Connection
Danger
！
When carrying the out connection between PV array and inverter, the PV array
should be covered with opaque materials and the DC-side circuit-breaker should
be disconnected, otherwise, the PV array may generate dangerous volta ge,
cause casualty. The Non-professionals do not make the connection operation.
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.
