Safety measures and safety equipment must comply with the respectively valid
national on site specifications. All externally connected devices shall comply with
the relevant safety standards applicable for the place of installation.
We recommend using connecting cables and connecting terminals according
to rated current (I
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
resistant cables.
For the connection of position transmitters, screened cables must be used.
Signal and fieldbus cables are susceptible to interference. Motor cables are
interference sources.
This product potentially causes high frequency interference!
The measures eliminating interference described hereafter must be observed
for cable installation in accordance with EMC.
Use shielded power cable and earth shield at both ends.
Lay cables being susceptible to interference or sources of interference at the
highest possible distance from each other.
The interference immunity of signal and fieldbus cables increases if the cables
are laid close to the earth potential.
If possible, avoid laying long cables and make sure that they are installed in
areas being 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.
Twisted wire pair, shielded.
For cable length <1,500 m: Cross section min. 0.2 mm²
For cable length >1,500 m: Cross section min. 0.5 mm²
Multiple-twisted pair cables must not be used.
Prior to installation, please note:
Connection is made as point-to-point topology.
Respect a distance of minimum 20 cm between HART cables and other cables
if possible. The cables should be laid in a separate, conductive, and earthed
cable tray, if possible.
Make sure that there are no potential differences between participants.
Maximum cable length depends on characteristics of devices connected (im-
pedance), of cables used (cable capacity and resistance) and the impedance
of all devices installed between two end devices.
