General Notes on Installation
As component parts of machines, facilities and systems, electronic control systems must
comply with valid rules and regulations, depending on their field of application.
General requirements concerning the electrical equipment of machines and aiming at the
safety of these machines are contained in Part 1 of European Standard EN 60204 (corresponds
to VDE 0113).
Information
In order to safely install c250-S Safety System, please read section

Project Planning and Installation and following.
Interference emission
Interfering emission of electromagnetic fields, HF compliant to EN 55011, limiting value class A,
Group 1
Information
If the controller is designed for use in residential areas, high-frequency
emissions must comply with limiting value class B as described in EN 55011.
Fitting the controller into earthed metal cabinets and installing filters in the
supply lines may produce a shielding compliant to the above standard.
The design and immunity to interference of programmable logic controllers are internationally
governed by standard IEC 61131-2:2007 which, in Europe, has been the basis for European
Standard EN 61131-2:2007 .
Note
Refer to IEC 61131-4, User's Guideline, for general installation instructions to be
complied with to ensure that hardware interface factors and the ensuing noise
voltages are limited to tolerable levels.
Electrical immission safeguard
To eliminate electromagnetic interference, connect the control system to the protective earth
conductor. Practice best cable routing.
Cable routing and wiring
Keep power circuits separate from control circuits:
•
DC voltages
60 V ... 400 V
•
AC voltages
25 V ... 400 V
Joint laying of control circuits is allowed for:
•
shielded
data signals
•
shielded
analogue signals
•
unshielded
digital I/O lines
•
unshielded
DC voltages < 60 V
•
unshielded
AC voltages < 25 V
