Arrangement of the
control cabinet
The arrangement of the components in the control
cabinet has a significant influence on the correct
operation of the machine or plant. When planning,
designing and installing the equipment, ensure that
the power section and the control section are
separated from one another. The power section
includes:
Contactors
Coupling modules
Transformers
Frequency converters
Power converters
DC power supply units
In order to effectively eliminate electromagnetic
interference, we recommend subdividing the control
cabinet into sections according to the different
power and interference levels. Simple partitions are
often sufficient to reduce interference in small control
cabinets.
Ventilation
In order to ensure that the PS4-200 is adequately
cooled, a minimum clearance of 5 cm (2
″
) must be
allowed between other components and the
ventilation slots in the housing. The values specified
in the technical data must be observed
(see Appendix).
Device arrangement
The PS4-200 should be installed horizontally in the
control cabinet as shown in the following figure.
