The EN 60529 standard covers the protection of electrical equipment by means of housings, covers or equivalent, and includes:
The degrees of protection are specified by abbreviations comprising the code letters IP and two digits.
Degree of protection | First digit
| Second digit
|
---|---|---|
IP20 (Standard) | Protected against solid foreign matter | No water protection |
IP21 (Option M21) | Protected against solid foreign matter | Protected against drip water Vertically falling water drops shall not have a harmful effect. |
IP23 (Option M23) | Protected against solid foreign matter | Protected against spray water Water sprayed on both sides of the vertical at an angle of up to 60° shall not have a harmful effect. |
Cabinet Modules fulfill the criteria for degree of protection IP20 as standard. The other degrees of protection outlined here are available as an option.
Unless specified otherwise, the following technical specifications are valid for all the following components of the SINAMICS S120 Cabinet Modules.

Radio interference suppression | SINAMICS drive converter systems are not designed for connection to the public grid (first environment). Radio interference suppression is compliant with the EMC product standard for variable-speed drives EN 61800-3, "Second environment" (industrial line supplies). The equipment can cause electromagnetic interference when it is connected to the public network. However, if supplementary measures are taken (e.g. → line filter), it can also be operated in the "first environment". |
1) In transport packaging.
2) Deviations with respect to the specified class are underlined.
The most important directives and standards are listed below. These are used as basis for the SINAMICS S120 Cabinet Modules and they must be carefully observed to achieve an EMC-compliant configuration that is safe both functionally and in operation.
