A3.9.2 Low Voltage Directive
(1) Requirements of Low Voltage Directive
The Low Voltage directive is applicable to equipment that operates with a rated voltage
between 50 to 1000V AC or between 75 to 1500V DC. It requires equipment to be
manufactured according to safety considerations and not pose risks of injury or death to
personnel, livestock, or damage to property when used in applications for which they are
designed.
This section summarizes the considerations to ensure that the FA-M3 conforms to the
Low Voltage directive. The installation manufacturer needs to test and confirm the
conformity to the Low Voltage directive of the finished product incorporating the FA-M3.
(2) Applicable Standards of the Low Voltage Directive
EN61010-1
Safety requirements for electrical equipment for measurement, control and laboratory
use
Part 1: General Requirements
EN61010-2-201
Safety requirements for electrical equipment for measurement, control and laboratory
use
Part 2-201: Particular requirements for control equipment
EN 61010-2-030
Safety requirements for electrical equipment for measurement, control and laboratory
use
Part 2-030: Particular requirements for testing and measuring circuits
The Low Voltage directive is not applicable to modules that operate with a rated voltage
of less than 50V AC or less than 75V DC. Modules that bear the CE declaration of
conformity and fall within the scope of the Low Voltage directive satisfy the requirements
of the above standards.
EN 61010-2-030 should be applicable to measuring circuits of measurement equipment,
and is applied only to analog input circuits of FA-M3 series.
The analog input terminals of the FA-M3 have no measurement categories. Therefore it
can’t use for measurement on Mains Circuit.
For details on modules conforming to the CE Marking, see Appendix A2,
“Approved/Compliant modules.”
