Installing Cables
If you choose the ground point on
the enclosure for connecting a
ground cable, prepare the ground
cable.
If you choose the ground point in
the maintenance compartment for
connecting a ground cable, use an
AC output cable that includes a
ground cable instead of preparing
an extra ground cable.
When using outdoor copper cables for
AC connection, select copper wiring
terminals. For requirements on the
cables and terminals of other
materials, see the
PV cable that meets the
1100 V standard

communications cable.
