International Standards
• The standards indicated in the “Standards” column are
those current for UL, CSA, cULus, cUL, NK, and Lloyd
standards and EC Directives as of the end of May 2008.
The standards are abbreviated as follows: U: UL, U1: UL
Class I Division 2 Products for Hazardous Locations, C:
CSA, UC: cULus, UC1: cULus Class I Division 2 Products
for Hazardous Locations, CU: cUL, N: NK, L: Lloyd, and CE:
EC Directives.
• Ask your OMRON representative for the conditions under
which the standards were met.
● EC Directives
The EC Directives applicable to PAC’s, PLC’s include the
EMC Directives and the Low Voltage Directive. OMRON
complies with these directives as described below.
●
EMC Directives Applicable Standards
EMI: EN61000-6-4, EN61131-2
EMS: EN61000-6-2, EN61131-2
PAC’s, PLC’s are electrical devices that are incorporated
in machines and manufacturing installations. OMRON
PAC’s, PLC’s conform to the related EMC standards so
that the devices and machines into which they are built
can more easily conform to EMC standards. The actual
PAC’s, PLC’s have been checked for conformity to EMC
standards. Whether these standards are satisfied for
the actual system, however, must be checked by the
customer.
EMC-related performance will vary depending on the
configuration, wiring, and other conditions of the equipment
or control panel in which the PAC, PLC is installed. The
customer must, therefore, perform final checks to confirm
that the overall machine or device conforms to
EMC standards.
● Low Voltage Directive
Applicable Standard:EN61131-2
VDC must satisfy the appropriate safety requirements.
With PAC’s, PLC’s, this applies to Power Supply Units and
I/O Units that operate in these voltage ranges.
These Units have been designed to conform to
EN61131-2, which is the applicable standard for PAC’s
and PLC’s.
