COMPLIANCE WITH EC DIRECTIVES
1. WHAT ARE EC DIRECTIVES?
The EC Directives were issued to standardize the regulations of the EU countries and ensure smooth
distribution of safety-guaranteed products. In the EU countries, the Machinery Directive (effective
in January, 1995), EMC Directive (effective in January, 1996) and Low Voltage Directive (effective
in January, 1997) of the EC Directives require that products to be sold should meet their fundamen-
tal safety requirements and carry the CE marks (CE marking). CE marking applies to machines and
equipment into which servo amplifiers have been installed.
(1) EMC directive
The EMC directive applies to a machine/equipment which incorporates the servo, not to the
servo alone. Hence, the EMC filter must be used to make this machine/equipment which incor-
porates the servo comply with the EMC Directive. For specific methods to comply with the EMC
Directive, refer to the "EMC Installation Guidelines" (IB(NA)67310).
This servo has been approved by TUV, third-party evaluation organization, which confirmed
that it can comply with the EMC Directive in the methods given in the "EMC Installation Guide-
lines".
(2) Low voltage directive
The low voltage directive applies also to the servo alone. Therefore, our servo is designed to
comply with the Low Voltate Directive.
This servo has been approved by TUV, third-party evalution organization, which confirmed that
it complies with the Low Voltage Directive.
(3) Machinery directive
Since the servo amplifiers are not machines, they need not comply with this derective.
2. PRECAUTIONS FOR COMPLIANCE
(1) Servo amplifiers and servo motors used
Use the following models of servo amplifiers and servo motors:
Servo amplifier series: MR-J2-10A to MR-J2-350A
Servo motor series
(2) Structure
(3) Environment
Operate the servo amplifier at or above the contamination level 2 set forth in IEC664. For this
purpose, install the servo amplifier in a control box which is protected against water, oil, car-
bon, dust, dirt, etc. (IP54).
(4) Power supply
1) Operate the servo amplifier to meet the requirements of the overvoltage category II set forth
in IEC664. For this purpose, a reinforced insulating transformer conforming to the IEC or EN
Standard should be used in the power input section.
2) When supplying interface power from external, use a 24VDC power supply which has been
insulation-reinforced in I/O.
