It will not touch the raid array--except to start it if it can--as long 
as you select custom partitioning, for example, and do not mount it. 
Start the install and when you are offered default partitioning select 
instead custom partitioning.  See if the partitioner shows your drive. 
If it sees it, you now have the opportunity to specify its mount point. 
  If it doesn't and you are installing the OS elsewhere anyway, install, 
then see if the array is seen.  If the array is not seen and you are not 
comfortable going forward, you can ctr-alt-delete out of the install.
