If only one ITxx module is used, it can be screwed to the metal spacers
using the M4 nuts (and washers) provided.
If a second ITxx module is used, the first ITxx module is not screwed using
the nuts, but instead, using plastic spacers (these are included with the ITxx
modules).
The second ITxx module can then be inserted on the plastic spacers, and
screwed together using the M4 nuts (and washers).
After the module assembly has been screwed together, it is inserted into the
subrack.
5.5.7 Application information and noise immunity
• Operation without fans is possible
• Noise immune operation is only possible, if it is tightly screwed into the
subrack.
For more detailed information on EMC and the ambient conditions, refer to
