Cable requirements
Cable specifications
● When installing sensor cable, use cable with at least same degree of protection as the
sensors. It is recommended to use cables supplied by Siemens:
– blue cables for installation of intrinsically safe circuits in hazardous areas
– gray cables for installation of non-intrinsically safe circuits
Further information on Siemens-supplied cables, see Cables and cable entries (Page 236).
● The wire length inside the connection compartment, from the cable gland to the terminals,
must be kept as short as possible. Wire loops in the terminal compartment must be avoided.
● To guarantee the degree of ingress protection, ensure that both ends of the cables are
given equivalent protection from ingress of moisture.
WARNING
Cable requirements
Cables must be suitable for the temperature (at least 70 °C) and be flammability-rated to at
least V-2.
Note
Output cables
If long cables are used in noisy environments, it is recommended to use shielded cables.
