NOTICE: If devices, such as office equipment, that is sensitive to noise are installed in the same location, separate the ground wires
and use independent grounds or noise filters to prevent noise from entering the devices through the ground wire. Otherwise, the office
equipment may fail.
Note: 1. Connect the regenerative units to power supply transformers on a 1:1 basis and use independent grounds. Otherwise the regenerative
units or the devices may fail to operate.
2. If other devices are installed in the same location, connect them while observing the grounding standards for each device. Otherwise
the regenerative units or the devices may fail to operate.
Do not loop the ground wire of the regenerative unit and the drive.
■ Wiring the Main Circuit Terminal
WARNING! Electrical Shock Hazard. Shut off the power supply to the regenerative unit before wiring the main circuit terminals. Failure
to comply may result in death or serious injury.
Wire the main circuit terminals after the terminal board has been properly grounded.
■ Main Circuit Connection Diagram
Refer to Main Circuit Connection Diagram on page 40 when wiring terminals on the main power circuit of the
