Precautions for Correct Use

 If you use a DC power supply for the main power and control power, connect the positive side to

L1 and L1C on the terminal block (TB1) and connect the negative side to L3 and L3C.

 Time is required to discharge power when the main power is turned OFF. High voltages remain

inside the Servo Drive even after the power supply is turned OFF. Take sufficient precautions

against electric shock. Before carrying out wiring or inspection, turn OFF the main power supply

and wait for at least 15 minutes.

 Do not connect the power supply to the B1 or N terminal. Internal elements may be destroyed.

 Do not connect or disconnect the terminal block while the main power supply is ON. Arcs may

cause burning.
