
Before turning on the driver input power, ensure that the input power supply specifications
indicated on the nameplate are consistent with those of the grid.

The electromagnetic contactor is used to switch on or off the main-circuit power supply of the
servo drive. Do not use this contactor to start or stop the servo drive.

In the figure, as the external regenerative brake resistor is connected, the short-connection cable
between B2 and B3 must be removed. For details about the connection, see section 3.2 "Main
circuit terminal wiring". The resistor must be installed on nonflammable material with good heat
dissipation performance, such as metal.
