3.9 Cabinet specifications
The complete ecosine max series has been type tested and qualified using reference standard cabi-
nets from the manufacturer Rittal, series VX25. Schaffner recommend using the reference cabinet
from Rittal series VX25 matching the filter size selected. The filter can be integrated in any standard or
customized cabinet according to the same specifications as the reference cabinets. Exact parts num-
ber of the reference cabinet are listed in Table 24. Usage of a cabinet that is not according to these
specifications, especially any deviations from the cooling requirement and air inlet configuration (see
section 3.10) might require additional validation from the customer. Schaffner is not reliable for any de-
viations in the filter specifications resulting from an improper cabinet integration.
