accommodated with minimal, if any, rewiring. This capability ensures that link power
technology can be adapted to both old and new projects, widening the potential market
for link power-based products. Finally, free topology permits link power systems to be
expanded in the future by simply tapping into the existing wiring where it is most
convenient to do so. This reduces the time and expense of system expansion, and from
the customer's perspective, keeps down the life cycle cost of the link power network.
