NO TE
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.

The specications are 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 cross-sectional area of the PE cable produces a conductance
equivalent to that of the cable specied in this table. The specications of the
PE cable are subject to this table or calculated according to IEC 60364-5-54.
Connecting the PE Cable
Step 1 Secure the PE cable using the ground screw.
