1) Apply the rated torque to terminal screws. Loose terminal screws can cause a short circuit or other malfunction. Over
tightening the terminal screws/bolts may permanently damage the terminals.
2) Use copper (Cu) wires only with 600V, 75Ԩ ratings. For 10~15HP 240V drives, R, S, T and U, V, W terminals are only for
use with insulated ring type connectors.
