AC output
power cable
(OT/DT
terminal)
If you connect a PE cable
to the PE point on the
enclosure, you are
advised to use a
three-core (U, V, and W)
outdoor copper cable and
M10 OT/DT terminals
(U, V, and W).
If you connect a PE cable
to the PE point in the
maintenance
compartment, you are
advised to use a four-core
(U, V, W, and PE)
outdoor copper cable,
M10 OT/DT terminals
(U, V, and W), and M8
OT/DT terminals (PE).
You do not need to
prepare a PE cable
separately.

The specifications are valid only if the conductors of the PE cable and AC power cable use the same material. If
the materials are different, ensure that the conductor cross-sectional area of the PE cable produces a
conductance equivalent to that of the cable specified in the table.
