Arrangement of the
control cabinet
The arrangement of the components in the control
cabinet has a significant influence on the way the
equipment or machines work. When planning,
designing and installing the equipment, ensure that
the power section and control section are kept
separate from one another. The power section
includes:
Contactors
Coupling modules
Transformers
Frequency converters
Power converters
DC power supply units
To effectively eliminate electromagnetic interference,
we recommend subdividing the control cabinet into
sections for the different power and interference
levels. Simple partitions are often sufficient to reduce
interference in small control cabinets.
Ventilation
A minimum clearance of 5 cm must be allowed
between other components and the ventilation slots
of the housing to ensure that the PS 4-300 is
adequately cooled. The values specified in the
technical data (see Appendix) must be observed.
