Section 2.1.3 Electromagnetic Compatibility
3BSE 002 415R701 Rev A 2-3
Some alternatives, in addition to those offered by other standard cabinets, follow:
• Sealed cabinet pressurized by clean, dehydrated instrument air.
• Gas cleaning by chemical filter.
• Use of dehydrated air.
•Dust filter.
• Sealed cabinet cooled by a heat exchanger.
It is reasonable to assume that a heat exchanger may be inoperative for short periods.
Under these conditions, the temperature in a cabinet must not exceed 70
°
C.
For further information about the environmental immunity, please refer to the data sheet
“ABB Master Environmental Immunity”.
Temperature
It is important to note the temperature within cabinets and in the surrounding environment and
atmosphere. Lower temperatures mean increased system reliability and availability.
The lives of wet, electrolytic capacitors and most semiconductors are greatly reduced if the
maximum permitted temperatures are exceeded.
For more information on design considerations, see Section 3.1.10.2, Heat Dissipation
Permitted in Cabinets.
Vibration
The cabinets must stand on a stable floor, deck or supporting structure, free from vibrations.
If the system equipment is installed in a control room adjacent to large machinery such as
shakers or large presses, where frequent major vibrations occur, shock absorbers or an isolation
pad may be required to protect the system equipment. Shock absorbers normally protect the
equipment from sustained low-level vibrations (vibrations that are perceptible, but not
excessive). If vibrations or shock are a major problem, consider more extreme measures to
alleviate the problem.
2.1.3 Electromagnetic Compatibility
Interference-free operation requires well-considered planning and realization of the installation,
especially with respect to grounding, cable selection and cable routing. Some notes are given in
the following sections from a planning viewpoint, while the setup instructions give you detailed
information about the actual realization of the installation.
For more information, both theoretical and practical, on the subject of Electromagnetic
Compatibility including interference, interference sources and suppression measures,
see separate reference documents.
You can obtain CE-marking according to EMC Directive 89/336/EEC for your Advant
Controller 450 provided appropriate cabinetry is selected. Please, refer to the ordering
documentation.
