Connection of Converter Control Power Supply Output
Connect converter control power supply output terminals P1 and N1 to
inverter left-side control power supply input terminals P1 and N1 using
exclusive-use power cable.
4. Wiring Precautions for Inverter Main Circuit Output
Connection of Terminal Block and Load
Connect output terminals U/T1, V/T2 and W/T3 to motor lead wires U, V
and W. The connection method is indicated on the back of the terminal
cover. Verify that the motor rotates in the forward direction (CCW: coun-
terclockwise when viewed from the motor load side) with the forward run
command.
Connection of Input Power Supply to Output Terminals Prohibition
Never connect the AC main circuit power supply to the output terminals U/
T1, V/T2 and W/T3.
Strict Prohibition of Short Circuiting or Grounding of Output Circuit
Never touch the output circuit directly or put the output line in contact with
the inverter case. Doing so may cause an electric shock or grounding. In
addition, never short circuit the output line.
Phase Advancing Capacitor or LC/RC Noise Filter Connection Prohibition
Never connect a phase advancing capacitor or LC/RC noise filter to the
output circuit.
Avoidance of Installation of Magnetic Starter
Do not connect a magnetic starter or magnetic contactor to the output cir-
cuit. If the load is connected while the inverter is running, the inverter
overcurrent protective circuit is activated because of inrush current.
