AUMA SAR 07.2 Operation Instructions

Cable installation in ac-
cordance with EMC
Signal and fieldbus cables are susceptible to interference. Motor cables are
interference sources.
●
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.
HART cable recommend-
ation:
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.
