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.

The specifications are 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 cross-sectional area of the PE cable produces a conductance
equivalent to that of the cable specified in this table. The specifications 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.
