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.
