Step3 Power Terminal Wiring
The following illustrations show the terminal layout of the power terminals for each of the inverter
ratings. Refer to the label and descriptions to understand the function and location of each
terminal before making wiring connections. Ensure that the cables selected meet or exceed the
specifications in 1.5 Cable Selection on page 7 before installing them.
• Apply rated torques to the terminal screws. Loose screws may cause short circuits and
malfunctions. Tightening the screw too much may damage the terminals and cause
short circuits and malfunctions.
• Use copper wires only with 600 V, 75 rating for the power terminal wiring, and 300
V, 75rating for the control terminal wiring.
• Do not connect two wires to one terminal when wiring the power.
Power supply wiring must be connected to the R, S, and T terminals. Arrangement of
the phase sequence is not necessary. Connecting them to the U, V, W terminals causes
internal damages to the inverter. Motor should be connected to the U, V, and W
Terminals.
