Notes:
- If shielded supply (input) cable is used, and
the conductivity of the shield is not sufficient
(see the table below), use a cable with a
ground conductor (1) or a separate PE cable
(2).
- For motor cabling, use a separate ground
cable (3) if the conductivity of the cable shield
is not sufficient (see the table below) and the
cable has no symmetrical ground conductors.
