C.1.3 Use of CE compliant components
The following points should be considered:
HUsing CE approved components will not guarantee a CE compliant system!
HThe components used in the drive, installation methods used, materials selected for interconnection of components are important.
HThe installation methods, interconnection materials, shielding, filtering and earthing / grounding of the system as a whole will determine CE compliance.
HThe responsibility of CE mark compliance rests entirely with the party who offers the end system for sale (such as an OEM or system integrator).
C.1.4 EMC wiring technique
Cabinet
Using a typical electroplated zinc coated enclosure, connected to earth/ground, means that all parts mounted on the back plane are connected to earth/ground and all outer shield (screen) connections can be connected to earth/ground. Within the cabinet there should be a spatial separation between power wiring (motor and AC power cables) and control wiring.
Shield (screen) connections
All connections between components must use shielded cables. The cable shields must be connected to the enclosure. Use conductive clamps to ensure good earth/ground connection. With this technique, a good earth/ground shield can be achieved.
EMC filters
The filter should be mounted next to the MicroFlex e100. The connections between the MicroFlex e100 and the filter should use shielded (screened) cables. The cable shields should be connected to shield clamps at both ends.
Earthing/grounding
For safety reasons (VDE0160), all Baldor components must be connected to earth/ground with a separate wire. Earth/ground connections must be made from the central earth/ground (star point) to the regeneration resistor enclosure and from the central earth/ground (star point) to the power supply.
