* Apply the rated torque to terminal screws.
* Loose screws can cause of short circuit or malfunction. Tightening the screw too much can damage the terminals and
cause a short circuit or malfunction.
* Use copper wires only with 600V, 75℃ ratings.
For 7.5~11kW 240V type inverters, R(L1), S(L2), T(L3) and U, V, W
terminals are only for use with insulated ring type connector.
