1.7 EMC-compliant Installation

Follow the same guidelines for filter installation as for drive installation. For EMC-compliant installation guidelines, refer to the drive
design or installation guide, and follow the electrical installation instructions.
• Shielded cables or unshielded cables within metal conduit are required between the filter and the drive, and between the filter
and the motor.
• Connect the shield to the filter at both ends.
• Provide a minimum 200 mm (7.9 in) separation, if possible, between mains input, motor cables, and control cables.
• Convey the currents back to the unit using the included EMC plate. Ensure good electrical contact from the EMC plate through
the mounting screws to the filter chassis. The EMC plate must be mounted during filter installation.
