Important: The grounding requirements vary by country and by application.
All installations must comply with national and local codes. Consult local and
national codes for specific grounding and bonding requirements for the desired
installation.
Important: Installers must make allowance for the amount of power that can be
fed into a distribution panel and the means and location for feed-in, in
accordance with NEC 2005 article 690.64 or similar requirements of the local
electrical code.
Important: If a Xantrex XW Conduit Box is installed, communication and Battery
Temperature Sensor cables must run through the raceway at the rear of the
Xantrex XW Conduit Box. Before making AC and DC connections, route all
communication and Battery Temperature Sensor cables through the raceways.
The raceways becomes more difficult to access after all AC and DC wiring is
completed.
