Details of the enclosure
Degree of protection
The degree of protection depends on the enclosure size and the parts used such as cable entries,
dummy plugs and climate nozzles. The nameplate specifies the degree of protection for which
the enclosure is designed. The minimum degrees of protection are:
• Device group II: IP54 to IP66 (Zone 1)
• Device group II: IP64 to IP66 (Zone 21)
Operating temperature
The operating temperature range of the enclosure depends on the temperature range of the
parts used, and can differ from the actual operating temperature range:
•
The nameplate specifies the permissible operating temperature range in each case.
• The maximum permissible operating temperature of the components and the power
dissipation occurring in the enclosure may limit the ambient temperature range for the total
configuration. This is checked at the factory for each cabinet. This calculation may differ from
the results of the TIA Selection Tool, since reserve modules are also taken into account.
Climate nozzles provide pressure compensation and drainage in the event of varying climatic
conditions.
• In the case of aggressive environments, check whether use of the enclosure is possible with
the material in question.
Cable and wiring entries (CWE)
• When fitting cables, observe the manufacturer's data on the tightening torques of the cable
and wiring entries.
• Use the tightening torque of the clamping screw when connecting the cables.
• Relieve the tension on the cables outside the enclosure so that the cable gland is not stressed.
• For additional information and technical specifications, refer the respective manufacturer
documentation, in particular:
– Technical specifications, clamping ranges for cables
– Notes on use, installation, mounting, commissioning and maintenance
Note
Use the supplied red dummy plugs to close any cable glands not in use. Only then is it ensured
that the degree of protection is retained.
