1.4 EMC/ESD measures

1.4.1

Electromagnetic compatibility (EMC)

RI suppression measures
Shielded signal cables
•
To ensure safe, interference-free operation of the system, the cables specified
in the individual drawings must be used.
•
Both ends of the shield must always be connected conductively with the
housings.
Exception:
If non-Siemens devices are connected (printers, programming devices, etc.),
you can also use standard shielding cables, which are connected at one end.
These external devices may not be connected to the control during normal
operation. However, if the system cannot be operated without them, then the
cable shields must be connected at both ends. Furthermore, the external
device must be connected to the control via an equipotential bonding cable.
Rules for routing cables
In order to achieve the best-possible noise immunity for the complete system
(control, power section, machine) the following EMC measures must be observed:
•
Signal cables and load cables must be routed at the greatest possible
distance from one another.
•
Only cables supplied by SIEMENS may be used as signal cables to and from
the NCU and PLC.
•
Signal cables must not be laid in the close vicinity of strong magnetic fields
(e.g., motors and transformers).
•
Pulse-carrying HC/HV cables must always be laid completely separately from
all other cables.
•
The distance (interference injection area) between the following cables must
be as close as possible:
- Signal cable and signal cable
- Signal cable and associated equipotential bonding lead
- Equipotential bonding lead and protective conductor incorporated in lead.
