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 AC drop cables.
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 a permanent end cap: It is purely for protecting the inverter
connectors during shipping. 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.
ATTENTION
Do not allow the cable to lie in contact with the roof surface. If necessary, route the
cable neatly along the racking using cable clips.
!
ATTENTION
To avoid damaging the inverter or cables, do not force together the AC Drop Cable
and inverter AC connectors. The connectors are keyed to prevent misalignment.
• Observe the direction of the drop cable connector: it should have a light-colored
triangle-shaped orientation mark. The inverter AC Out connector has the same
mark for orientation purposes. See “Figure 27. T-Cable to Inverter AC Connector”
on page 33 for details.
• Do not twist the cabling in the process of connection-- tension can damage the
cable and connectors over time.
