shock whether the module is connected
or disconnected.
The shock hazard increases as modules
are connected in parallel, producing
higher current, and as modules are
connected in series, producing higher
voltage.
The installer assumes the risk of all
personal injury or property damage that
might occur during installation and
handling of modules.
To avoid injury or damage:
