Maintenance and Servicing
•
Precautions regulation to be observed when measuring or checking a controller after
power-up.
•
Repairs may only be carried out by qualified Lenze personnel. Otherwiese warranty is lost.
•
Spare parts: Only use parts approved of by Lenze. Only genuine Lenze modules must be
used in modular controllers.
•
Modular systems: always plug or unplug modules in a power-down state. You may
otherwise damage the modules or (possibly not immediately recognizably!) inhibit their
functionality.
•
Always dispose of (rechargeable) batteries as hazardous waste.
Electromagnetic Compatibility
Definition
Electromagnetic compatibility is the ability of a device to function satisfactorily in its
electromagnetic environment without itself causing any electromagnetic interference that
would be intolerable to other devices in this environment.
Of all known phenomena of electromagnetic noise, only a certain range occurs at the location
of a given device. These kinds of noise are specified in the applicable product standards.
IEC 61131-2 which, in Europe, has been the basis for European Standard EN 61131-2.
Information
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 (corresponds
to VDE 0113).
