If the installation has strong electromagnetic sources of interference or
the electrical lines are more than 30 m long, use of shielded field cables is
recommended to achieve the specified data. To this end, the shield must be
connected to the equipotential bonding of the hazardous area and placed on
the shield busses in the enclosure as close to the entry point as possible.
The shield busses must also be connected to the mounting plate close to
the entry point of the field wiring using the shortest possible route.
See the "Grounding and shielding" instructions.
