• If you connect a ground cable to the
ground point on the device enclosure
and the neutral wire is not used, you
are advised to use a three-core (L1,
L2, and L3) outdoor cable and M12
OT/DT terminals (L1, L2, and L3).
• If you connect a ground cable to the
ground point in the maintenance
compartment and the neutral wire is
not used, you are advised to use a
four-core (L1, L2, L3, and PE) outdoor
cable, M12 OT/DT terminals (L1, L2,
and L3), and M10 OT/DT terminals
(PE).
• If you connect a ground cable to the
ground point on the device enclosure
and the neutral wire is used, you are

and N) outdoor cable and M12 OT/DT
terminals (L1, L2, L3, and N).
• If you connect a ground cable to the
ground point in the maintenance
compartment and the neutral wire is
used, you are advised to use a five-
core (L1, L2, L3, N, and PE) outdoor
cable, M12 OT/DT terminals (L1, L2,
L3, and N), and M10 OT/DT terminals
(PE).
You are advised to use a single-core
outdoor cable and M12 OT/DT
terminals.
