● If the ground point
on the enclosure is
used, three-core
(L1, L2, and L3)
outdoor cables and
M12 OT/DT
terminals (L1, L2,
and L3) are
recommended.
● If the ground point
in the maintenance
compartment is
used, four-core (L1,
L2, L3, and PE)
outdoor cables,
M12 OT/DT
terminals (L1, L2,
and L3), and M10
OT/DT terminals
(PE) are
recommended. You
do not need to
prepare a PE cable.

● The value of S
p
is valid only if the conductors of the PE cable and AC power cable use the
same material. If the materials are dierent, ensure that the conductor cross-sectional area of
the PE cable produces a conductance equivalent to that specied in this table. The
specications of the PE cable are subject to this table or calculated according to IEC
60364-5-54.
● For details about the installation procedure and precautions for cable stripping outside the
compartment, see 5.5 Requirements for AC Power Cable Stripping Outside the
Compartment.
5.3 Connecting a PE Cable
Precautions
● Preferentially connect the PE cable for the SUN2000 to the ground point on
the enclosure. The ground point in the maintenance compartment is used for
connecting to the PE wire of a multi-core AC power cable.
