By default, the xStorage Home system does not have a power
meter installed, as explained in the xStorage Home installation
manual. The Eaton certied installer should therefore provide
the end user with a power meter that will enable the full user
interface monitoring and functional capability of the system.
Please refer to the xStorage Home installation manual to
understand the power meters setup within the full system
conguration.
This power meters manual provides Eaton certied installers
with important instructions on how to install the power meters
that are compatible with xStorage Home.
This manual is complementary to the xStorage Home
installation manual and the xStorage Home user interface
