There is a diminishing return from each additional link from the same site, many links probably triggers the suspicion that you have bought site-wide blogroll or footer links from a site.

Be sure to be registered with Google Webmaster Tools so you are able to receive the dreaded "unnatural link pattern" warning, for which a time response, demonstrating an effort to remove bad links can avoid penalties. Some advice making backlinks removable on your end, most easily by changing the url of an inner page to shed all of it's links, consider that it's a lot harder to remove links to your home page, sone webmasters avoid home page links from this reason, at least linking to yoursite.com/index.html gives you an index page you can replace if worst comes to worst.
