6.1 Product lifecycle
During the product lifecycle, it may be necessary to upgrade the IED to a next-generation 
unit.  Although such an upgrade will not likely be necessary for a minimum of 20 years 
after the initial installation, it is wise to consider beforehand the product lifecycle when 
considering the original product.
IED-specified options can be found from the Retrofit Solutions Database at www.abb.com 
by following the links within ABB Service Guide or the ABB Product Guide that may be 
found on the product specific Service & Support sheet.
