1.4.4 EC Directive Electromagnetic Compatibility
(89/336/EEC)
amended by: First Amendment Directive (92/31/EEC)
CE Mark Directive (93/68/EEC)
General
l
The EC Electromagnetic Compatibility Directive is effective for ”devices” which may cause
electromagnetic interference or the operation of which may be impaired by such interference.
l
The aim is to limit the generation of electromagnetic interference such that an operation
without interferences of radio and telecommunication systems and other equipment is
possible. The devices must also show an appropriate resistance against electromagnetic
interference to ensure the application as directed.
l
Controllers cannot be operated on their own. Controllers cannot be evaluated on their own in
terms of EMC. Only after the integration of the controllers into a drive system, can this system
be tested concerning the objectives of the EC EMC Directive and the compliance with the
”Law about the Electromagnetic Compatibility of Devices”.
l
Lenze has evaluated the conformity of controllers on defined drive systems. These evaluated
drive systems are called ”CE-typical drive system” in the following.
Therefore, the user of the controllers can
– either determine the system components and their implementation into a drive system
himself and declare the conformity under his own responsibility,
– or install the drive system according to the CE-typical drive system evaluated by the
inverter manufacturer who has already proved the conformity.
Components of the CE typical drive system
System component Specification
Controller Controller types 93XX series
For the type designation refer to the first cover page
Mains filter A/B For data and filter assignment see chapter ”Ratings”
Motor cable Screened power cable with tinned E-CU braid with a minimum of 85% optical coverage.
Mains cable between mains filter
and controller
As from cable length 300 mm:
Screened power cable with tinned E-CU braid with a minimum of 85% optical coverage.
Control cables Screened signal cable type LIYCY
Motor Standard three-phase asynchronous motor, servo synchronous motor, servo asynchronous motor
Lenze types DXRA, MDXKX or similar
l
Controller, RFI filter and mains choke are located on a common mounting plate.
l
The system components were wired according to chapter 4 ”Electrical Installation”.
