Connecting a DC Reactor
When installing a DC reactor, remove the jumper between ter1 and +2 (terminals are jumpered for shipment).
The jumper must be installed if not using a DC reactor. Refer to
Figure 8.5 for an example of DC reactor wiring.

Reducing Radiated, Conducted, and Induced Noise
Drives generate noise that can potentially affect surrounding devices like PLCs, etc.
• Radiated Noise: Electromagnetic waves noise throughout the radio bandwidth radiated from the drive and cables.
• Conducted Noise: Noise generated by the drive and emitted to through the power lines.
• Induced Noise: Noise generated by electromagnetic induction can affect control signal lines.
Take the following measurements to prevent noise causing malfunction of other drives or devices:
• Install all components on a well grounded metal plate.
• Keep the motor cable as short as possible.
• Use noise filters on the input side of the drive to reduce conducted noise.
• Install noise filters on the input and output side of the drive, install the drive in a metal enclosure panel and use a
shielded motor cable to reduce radiated noise.
• Use shielded motor and control circuit lines and lay control circuit lines at least 30 cm away from power lines in order
to prevent malfunction due to induced noise.
