● 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 dierent, ensure that the conductor of the PE cable with a
proper cross-sectional area produces a conductance equivalent to that of the cable specied in
the table.
● The specications 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
aect cable selection include the rated current, cable type, routing mode,
ambient temperature, and maximum expected line loss.
