The MotiFlex e100’s protective earth connection does not provideelectromagnetic compatibility. Its purpose is to prevent exposed metalwork becoming live in thecase of a serious failure. To avoid EMC coupled effects within the panel design:1. Do not run AC filter input and output power cables in close proximity.2. Do not run motor output power cables with any other cables, especially Ethernet, signalcables, or ’clean’ AC power.3. Do not run power and signal cables in the same trunking. If the cables must run in parallel,they should be separated by 200 mm (8 in) or placed in separate metal trunking.4. If any of the above cables must cross, they must do so at 90 degrees to minimize coupling.5. Ensure all sources of electrical noise are suppressed, e.g. solenoids, relays, contactors.AC powerfrom fusesand reactorMount AC filter andMotiFlex e100 on thesame metal panel.Regeneration resistor.For long cables, useshielding as shown for ACpower cables.DO NOT TOUCH!Regeneration resistors canbecome extremely hot!Locate away from vulnerablecomponents and wiringConnect AC power cable shield tometal panel, using conductive shieldearth/ground clamps.Driveearthmust beat least10 mm 2(7 AWG)OPT-CM-001AC power wiresshould be as short aspossible, typicallyless than 0.3 m (1 ft).Longer wires mustbe shielded asshown.Wire colorsmay varyaccordingto region.CAUTIONFigure 7 - Panel layout best practice
