If you connect a ground cable to
the ground point on the chassis
shell, 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, you do
not need to prepare a PE cable but
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).

Note
[1]: 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 different, ensure that the conductor of the PE cable with a
proper cross
-sectional area produces a conductance equivalent to that of the cable specified in the
table.
The specifications of the PE cable are subject to this table or calculated according to IEC
60364
-5-54.
Note
[2]: For some models, the outer diameter of a single-
core cable ranges from 14 mm to 36 mm
based on the label in the maintenance compartment.
Preparations
4.1
•
S and S
p
are the conductor cross-sectional areas of AC power cables and PE cables respectively.
•
The cable diameter must comply with local cable standards.
•
The factors that affect cable selection include the rated current, cable type, routing mode,
ambient temperature, and maximum expected line loss.

Connecting Cables
•
Connect cables in accordance with the local installation laws and regulations.
•
To prevent poor cable connection due to overstress, leave enough slack before connecting the
cables to the appropriate ports.
