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. 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-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
Use a type B (AC/DC detectable type) breaker
Isolating
transformer
Circuit breaker
AC reactor
Electromagnetic
contactor
Drive unit
CB
MC
M
(2) Environment
Use the units under an Overvoltage Protection Category III and Pollution Class of 2 or less
environment as stipulated in IEC60664.
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.

(3) Power supply
[1] If a control power supply of the drive unit is 200V, use the power supply under an Overvoltage
Protection Category II as stipulated in IEC60664. In that case, insert a star-connection
isolation transformer that is compliant with EN or IEC Standard into the primary input power
supply of the drive unit.
[2] Do not omit the circuit breaker and electromagnetic contactor.
(4) Earthing
[1] To prevent electric shocks, always connect the servo/spindle drive unit protective earth (PE)
terminal (terminal with
mark) to the protective earth (PE) on the control panel.
[2] When connecting the earthing wire to the protective earth (PE) terminal, do not tighten the
wire terminals together. Always connect one wire to one terminal.
PE terminal
PE terminal
(5) Wiring
[1] Always use crimp terminals with insulation tubes so that the connected wire does not contact
the neighboring terminals.
Crim p termi nal
Insul ation tube
Wire
[2] Do not connect the wires directly.
