EMC-compliant Installation

1.6
For more information, refer to the operating or design guide.
Use shielded cables for motor output (unshielded cables in metal conduit are acceptable), brake, DC, and control wiring.

Ensure that motor, brake, and DC cables are as short as possible to reduce the interference level from the entire system. Provide a

minimum space of 200 mm (7.9 in) between mains input, motor cables, and control cables.
Convey the currents back to the drive using a metal mounting plate and proper EMC bonding clamps. Ensure good electrical

contact from the mounting plate through the mounting screws to the metal frame of the enclosure.
If the shield connection points have a voltage potential difference, connect a low impedance equalizing wire parallel to the shielded

cable.
When using relays, control cables, a signal interface, fieldbus, or brake, connect the shield to the enclosure at both ends. If the

ground path has high impedance, is noisy, or is carrying current, break the shield connection on one end to avoid ground current
loops.

SHOCK HAZARD

Touching an uncovered motor, mains, or DC connection plug or terminal can result in death or serious injury.
All plugs and terminal protection covers for the motor, mains, and DC connections must be installed

within the IP20 enclosure to provide an IP20 protection rating. If plug and terminal covers are not
installed, the protection rating is considered IP00.
