• An AC bus extension cable can connect one distribution unit to another.
• The grid connection cable connects an AC branch to the AC mains.
• The grid connection cable connectors should be connected to the AC mains
first, and to the AC branch distribution unit last.
WARNING: There must not be any exposed AC connection points. These AC
points will be live when the system is connected to the utility grid. Always
use the end caps provided to seal the open connection points on the
distribution units.
WARNING: Depending on the model used, the maximum number of micro
inverters in any AC branch must not exceed the maximum number allowed.
ATTENTION: A “protective cap” is not an end cap: it should stay on the
inverter connector to keep it dry during the installation process. Discard the
protective caps only while making the inverter connections. Do not attempt
to re-use protective caps.
