2 With a conduit: Use a separate grounding PE cable (2a), or a PE conductor (2b) inside the
conduit if the conductivity of the conduit does not meet the requirements for the PE
conductor (see page
89 ).
With a shielded cable: Use a separate grounding PE cable (2a) or a cable with a separate
PE conductor (2b) if the conductivity of the shield does not meet the requirements for the
PE conductor (see page
89 ).
Note: If the cross-section of the Cu PE conductor is less than 8 AWG, install a second Cu
PE conductor of the same cross-sectional area as the original PE conductor. Alternatively,
you can use a Cu PE conductor with at least 10 mm
2
cross-section. See page 21 .
3 With the conduit: Make sure of a proper grounding of the conduit at the cable entry. Ground
the other end of the conduit and PE conductor (if used) at the distribution board.
With a shielded cable: Do a 360-degree grounding if shielded cable is used. Ground the
other end of the input cable shield and PE conductor (if used) at the distribution board.
4 With the conduit: Make sure of a proper grounding of the conduit at the cable entry.
With a shielded cable: Do a 360-degree grounding of the shield.
5 External brake resistor (if used)
With a conduit: Use a separate grounding PE cable (5a), or a PE conductor (5b) inside the
conduit if the conductivity of the conduit does not meet the requirements for the PE
conductor (see page
89 ).
With a shielded cable: Use a separate grounding PE cable (5b) or a cable with a separate
PE conductor (5b) if the conductivity of the shield does not meet the requirements for the
PE conductor (see page
89 ).
