4.1 Basic rules
Deactivation of the safety function through conducted interference
sources!
All nodes of the safety-relevant communication must be certified
according to IEC 61010 or must have a corresponding EC conformity
declaration.
All PROFIsafe devices used on the bus must have a PROFINET and a
PROFIsafe - certificate.
All safety devices must also have a certificate from a "Notified Body"
(e.g. TÜV, BIA, HSE, INRS, UL, etc.).
The 24V power supplies used must not cut out in the event of a fault in
the energy supply (safe under single fault conditions) and must fulfil
SELV/PELV.
Only cables and connectors which are provided with a PROFINET
manufacturer's declaration are to be used.
The shielding effect of cables must also be guaranteed after
installation (bending radii/tensile strength!) and after connector
changes. In cases of doubt, use more flexible cables with a higher
current carrying capacity.
Only use M12 connectors for connecting the measuring system, which
guarantee good contact between the cable shield and connector
housing. The cable shield must be connected to the connector housing
over a large area.
A 5-wire cable with a PE-conductor isolated from the N-conductor (so-
called TN network) must be used for the drive/motor cabling. This will
largely prevent equipotential bonding currents and the development of
interference.
A shielded and stranded data cable must be used to ensure high
electromagnetic interference stability of the system. The shielding
should be connected with low resistance to protective ground using
large shield clips at
both ends
. The shielding should be grounded
in
the switch cabinet only
if the machine ground is heavily
contaminated with interference towards the switch cabinet ground.
Equipotential bonding measures must be provided for the complete
processing chain of the system.
Power and signal cables must be laid separately. During installation,
observe the applicable national safety and installation regulations for
data and power cables.
Observe the manufacturer's instructions for the installation of
converters and for shielding power cables between frequency
converter and motor.
Ensure adequate dimensioning of the energy supply.
