Kendrion Kuhnke Automation GmbH
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.
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.
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 (same as VDE 0113).
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

AC voltages
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
Location of installation
Ensure that temperatures, contaminations, impact, vibration or electromagnetic interference are no
impediment to the installation.
Temperature
Consider heat sources such as general heating of rooms, sunlight, heat accumulation in assembly rooms or
control cabinets.
Contamination
Use suitable casings to avoid possible negative influences due to humidity, corrosive gas, liquid or
conducting dust.
Impact and vibration
Consider possible influences caused by motors, compressors, transfer lines, presses, ramming machines
and vehicles.
Electromagnetic interference
Consider electromagnetic interference from various local sources: motors, switching devices, switching
thyristors, radio-controlled devices, welding equipment, arcing, switched-mode power supplies, converters /
inverters.
