EMC Directive 89/336/EEC This controller is a component intended for implementation in
machines or systems for the industrial environment. It has been tested
to meet the Council Directive 89/336 Electromagnetic Compatibility
(EMC) and all applicable standards.
Important: The conformity of the controller and filter to any standard
does not guarantee that the entire installation will con-
form. Many other factors can influence the total installa-
tion and only direct measurements can verify total con-
formity. It is therefore the responsibility of the machine
manufacturer, to ensure, that the conformity is met.
Essential Requirements for a Conforming EMC Installation
1. An input line filter module (see “Accessories” in Appendix A)
must be installed to reduce conducted emissions. When using the
filters listed in Appendix A, the maximum motor cable lengths
must be 75 meters (250 feet) for controllers rated 200-240VAC,
and 40 meters (133 feet) for controllers rated 380-460VAC.
2. The controller system must be mounted in a shielded enclosure
to reduce radiated emissions.
3. Grounding of equipment and cable shields must be solid, with
low impedance connections.
4. Motor and control cables entering the shielded enclosure must
have EMC-tested shielded cable clamps, or grounded metal
conduit.
5. All motor cables must use shielded cable, or be in grounded metal
conduit.
6. All control and signal wiring must use shielded cable or be in
grounded metal conduit.
7. The Common terminals (TB3-3 & 7) must have a solid connection
to PE (protective earth).
