tional on site specifications. All externally connected devices shall comply with the rel-
evant safety standards applicable for the place of installation.
•
We recommend using connecting cables and connecting terminals according to
nominal current (I
). Refer to
N
•
For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
•
To avoid contact corrosion, we recommend the use of sealing agents for cable
glands and blanking plugs made of metal.
•
Use connecting cable with appropriate minimum rated temperature.
•
For connecting cables exposed to UV radiation (outdoor installation), use UV res-
istant cables.
•
For connecting electronic position transmitters, only use screened cables.
•
For connecting fieldbus cables or network cables, respect the cable recommenda-
tions for the respective fieldbus connection or network connection. Further inform-
ation is provided in the short instructions for fieldbus connection or network con-
nection (as far as available).
•
Signal and fieldbus cables or network cables are sensitive to interference. Motor
cables are interference sources.
•
Lay cables susceptible to interference or cables as sources of interference at a
large distance from each other.
•
If the cables a installed close to the ground potential, the immunity status of signal
and fieldbus cables or network cables is increased.
•
Lay cables in areas subject to low interference.
•
Avoid parallel paths with little cable distance of cables being either susceptible to
interference or interference sources.
•
In a residential environment, this product may cause radio interference, in which
case supplementary mitigation measures might be required.
