 Ensure that the input power voltage is within the acceptable range.
Caution
Overvoltages can damage the drive.
 If commercial power is connected to U, V, W terminals of Drive, they may be damaged. Be sure to
connect power to L1, L2, L3 terminals.
 Connect short-circuit pins to the B and BI terminals. For external regenerative resistors, remove the
short-circuit pins and use standard resistors for the B+ and B terminals.

 Configure the system so that the main power (L1, L2, L3) is supplied after the control power (C1,
C2). (Refer to section 2.4.1, “Power Supply Wiring Diagram.”)
 High voltages may remain in the device for sometime even after the main power is disconnected.
Please be careful.
Warnings
After disconnecting the main power, ensure that the charge lamp is off before you start wiring.
Failure to do so may result in electric shock.

Always ground the device over the shortest possible distance. Long ground wires are susceptible to
noise which may cause the device to malfunction.
