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 fundamental safety
requirements and carry the CE marks (CE marking). CE marking applies to machines and equipment into
which servo amplifiers have been installed.
The servo amplifiers do not function independently but are designed for use with machines and equipment.
Therefore, the CE marking does not apply to the servo amplifiers but applies to the machines and
equipment into which the servo amplifiers are installed.
This servo amplifier conforms to the standards related to the Low Voltage Directive to facilitate CE
marking on machines and equipment into which the servo amplifiers will be installed. To ensure ease of
compliance with the EMC Directive, Mitsubishi Electric prepared the "EMC INSTALLATION
GUIDELINES" (IB(NA)67310) which provides servo amplifier installation, control box making and other
procedures. Please contact your sales representative.
2. PRECAUTIONS FOR COMPLIANCE
The standard models of the servo amplifier and servo motor comply with the EN Standard. In addition to
the instructions provided in this Instruction Manual, also follow the instructions below. If the model is not
specifically described to comply with the EN Standard in this Instruction Manual, it has the same
specifications as those of the standard models:
(1) Structure
24VDC
power
supply
Circuit
protector
Reinforced
insulation type
Servo
amplifier
Servo
motor
SM
Control box
(2) 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, carbon, dust, dirt, etc.
(IP54).
(3) Power supply
Use a 24VDC power supply which has been insulation-reinforced in I/O.
(4) Grounding
To prevent an electric shock, fit the supplied earth terminal (E) to the servo amplifier and always
connect it to the earth (E) of the control box.
