Appendix 2. Compliance to EC Directives
A2 - 2
Appendix 2-1 Compliance to EC Directives
Appendix 2-1-1 European EC Directives
In the EU Community, the attachment of a CE mark (CE marking) is mandatory to indicate that the basic
safety conditions of the Machine Directives (issued Jan. 1995), EMC Directives (issued Jan. 1996) and
the Low-voltage Directives (issued Jan. 1997) are satisfied. The machines and devices in which the
servo and spindle drive are assembled are the targets for CE marking.
(1) Compliance to EMC Directives
The servo and spindle drive are components designed to be used in combination with a machine or
device. These are not directly targeted by the Directives, but a CE mark must be attached to
machines and devices in which these components are assembled. "MDS-C1 INSTRUCTION
MANUAL Appendix 1", which explains the unit installation and control panel manufacturing method,
etc., has been prepared to make compliance to the EMC Directives easier.
(2) Compliance to Low-voltage Directives
The MDS-C1 Series units are targeted for the Low-voltage Directives. An excerpt of the precautions
given in this specification is given below. Please read this section thoroughly before starting use.
A Self-Declaration Document has been prepared for the EMC Directives and Low-voltage
Directives. Contact Mitsubishi or your dealer when required.
Appendix 2-1-2 Cautions for EC Directive compliance
Use the Low-voltage Directive compatible parts for the servo/spindle drive and servo/spindle motor. In
addition to the items described in this instruction manual, observe the items described below.
(1) Configuration
CB MC M
Control panel
Circuit breaker
AC reactor
Electromagnetic
contactor
Servo/spindle drive
Motor
Isolating
transformer
Use a type B (AC/DC detectable type) breaker
(2) Environment
Use the units under an Overvoltage Protection Category III and Pollution Class of 2 or less
environment as stipulated in IEC60664.
(a) To attain the Overvoltage Category II, insert an EN or IEC Standard compliant star-connection
insulated transformer in the power supply unit input.
(b) To attain a Pollution Class of 2, install the servo/spindle drive unit in a control panel having a
structure (IP54 or higher) in which water, oil, carbon or dust cannot enter.
