Product Description:

The ground conductor of the motor cable should be connected to the drive ground (GRD) terminal directly. Connecting this ground conductor to a cabinet ground point or ground bus bar may cause high frequency current to circulate in the ground system of the enclosure. The motor end of this ground
conductor must be solidly connected to the motor case ground. Shielded or armored cable may be used to guard against radiated emissions from the motor cable. The shield or armor should be connected to the drive ground terminal and the motor ground as outlined in the Grounding section of this Installation
chapter. Common mode chokes are recommended at the drive output to reduce the common mode noise. An RFI filter can be used and in most situations provides an effective reduction of RFI emissions that may be conducted into the main supplylines. If the installation combines a drive with sensitive devices or circuits,it is recommended that the lowest possible drive PWM frequency be programmed.
