● If you connect a PE
cable to the ground
point on the
enclosure, 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 PE
cable to the ground
point in the
maintenance
compartment, 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). 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 of the PE cable with a
proper cross-sectional area produces a conductance equivalent to that of the cable specied in
the table.
● The specications of the PE cable are subject to this table or calculated according to IEC
60364-5-54.
● The cable diameter must comply with local cable standards.
● The factors that
aect cable selection include the rated current, cable type, routing mode,
ambient temperature, and maximum expected line loss.
