Follow the minimum component spacing requirements when designing the
electrical system layout. You can reduce noise by placing the modules at
least 50 mm apart. If this is not possible, install an electrically conductive
metallic shield plate between the units. Place all devices at least 100 mm
from the cabinet walls. For additional information on electrical system
design requirements refer to 4D-1.
ATTENTION: Do not install the control close to equipment,
such as an arc welder, power transformer, or large motor, that
generates high level noise.
