2.1 Control panel layout
The layout of the components inside the control panel is a major factor for
achieving interference-free functioning of the plant or machinery. During the
project planning and design phase, as well as its implementation, care must
be taken that the power and control sections are separated.
The power section includes:
• Contactors
• Coupling/interfacing components,
• Transformers,
• Variable frequency drives,
• Current converters.
In order to effectively exclude any electromagnetic interference, it is a good
idea to divide the system into sections, according to their power and interfer-
ence levels. In small control panels it is often enough to provide a sheet steel
dividing wall, to reduce interference factors.
2.1.1 ventilation
When designing the system, make sure that the Modular PLCs XControl: XC-
104-…, XC-204-…, XC-303-… are adequately ventilated.
In order to ensure that the maximum operating ambient temperature will not
be exceeded, make sure that there is enough clearance between the system
block's vents and any neighboring components, as well as between the
vents and the control panel's back plate.
Keep a minimum clearance of 50 mm from passive components. If the adja-
cent components are active elements (e.g., power supplies, transformers),
keep a minimum clearance of 75 mm instead.
CAUTION
Installation requires qualified electrician
DANGER OF ELECTRIC SHOCK!
All (de-)installation work must be carried out with the entire
installation in a de-energized state.
Follow the safety rules in DIN VDE 0105:
• De-energize and isolate the system.
• Secure against retriggering.
• Verify complete isolation from the supply.
• Earthing and short-circuiting.
• Cover or enclose any neighboring live parts.
