Appendix 3. Compliance with European EC Directives
A3 - 2
Appendix 3-1 Compliance to EC Directives
Appendix 3-1-1 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. The next section "EMC
Installation Guidelines", 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-R 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 3-1-2 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
Insert a type B circuit breaker (RCD) in the power supply side of the unit.
Isolating

Circuit breaker
AC reactor
Electromagnetic

(2) Environment
Use the units under an Overvoltage Category II and Pollution Class of 2 or less environment as
stipulated in IEC60664.
(a) To adjust the units to the Overvoltage Category II, insert an isolating transformer of the star
connection complying with EN or IEC standard in the input of the power supply unit.
(b) To adjust the units to the Pollution Class of 2, install the units in a control panel having a
structure
(IP54 or higher) in which water, oil, carbon or dust cannot enter.
