European Union Directives

Other Sources of Although the EMC Directive gets the most attention, other basic Directives, such as

Informationthe Machinery Directive and the Low Voltage Directive, also place restrictions on the control panel builder. Because of these additional requirements it is recommended that the following publications be purchased and used as guidelines:

SBSI publication TH 42073: February 1996 – covers the safety and electrical aspects of the Machinery Directive

SEN 60204–1:1992 – General electrical requirements for machinery, including Low Voltage and EMC considerations

SIEC 1000–5–2: EMC earthing and cabling requirements

SIEC 1000–5–1: EMC general considerations

Basic EMC Installation Guidelines

Enclosures	The simplest way to meet the safety requirements of the Machinery and Low Voltage
	Directives is to house all control equipment in an industry standard lockable steel
	enclosure. This normally has an added benefit because it will also help ensure that
	the EMC characteristics are well within the requirements of the EMC Directive.
	Although the RF emissions from the PLC equipment, when measured in the open
	air, are well below the EMC Directive limits, certain configurations can increase
	emission levels. Holes in the enclosure, for the passage of cables or to mount
	operator interfaces, will often increase emissions.
