4.4 Installing and wiring in compliance with EMC Directive
EMC Directives
The speed controller is designed and manufactured as a component to be installed within another device.
The EMC Directives require that your mechanical equipment in which the speed controller is installed
satisfy the applicable requirements. The installation/wiring methods of the speed controller explained
here represent the basic methods that are effective in helping your mechanical equipment conform to the
EMC Directives. The final level of conformance of your mechanical equipment to the EMC Directives
will vary depending on the control system equipment used with the speed controller, configuration of
electrical parts, wiring, layout, hazard level, and the like. Therefore, you must conduct the EMC tests on
your mechanical equipment to confirm compliance.
Applicable Standards
EMI
EN 55011 Group 1 Class A
EN 61000-6-4
EMS
EN 61000-6-2
Caution: This equipment is not intended for use in residential environments nor for use on a low-voltage
public network supplied in residential premises, and it may not provide adequate protection to
radio reception interference in such environments.
Effective measures must be taken against the EMI that the speed controller may give to adjacent
control-system equipment, as well as the EMS of the speed controller itself, in order to prevent a serious
functional impediment in the machinery. The use of the following installation and wiring methods will
enable the speed controller to be compliant with the EMC Directive.
