Appendix 6. Compliance to EU EC Directives
Appendix 6-1 Compliance to EC Directives
Appendix 6-1-1 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 6-1-2 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
Isolating transformer
Circuit breaker
Electromagnetic contactor
AC reactor
CB MC
Drive unit
M
Use a type B (AC/DC detectable type) breaker
(2) Environment
Use the units under an Overvoltage Category II and Pollution Class of 2 or less environment as stipulated in IEC60664.
These units do not provide protection against electric shock and fire sufficient for the requirements of the Low-voltage Directive and relevant European standards by themselves, so provide additional protection (refer to 5.2.4 and 7.1.6.1 of EN50178)

Appendix 6. Compliance to EU EC Directives
[1] Use the power supply and servo/spindle drive unit under an Overvoltage Category II as stipulated in IEC60664.
[2] In case of Overvoltage Category III, connect the PE terminal of the units to the earthed-neutral of the star-connection power supply system.
[3] 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
[3] Select the earthing wire size in accordance with Table 1 of EN60204-1.
(5) Wiring
[1] Always use crimp terminals with insulation tubes so that the connected wire does not contact the neighboring terminals.
Crimp terminal
Insulation tube
Wire
[2] Do not connect the wires directly.
[3] Select the size of the wires for input power supply to Power Supply unit in accordance with
Table 4 and 5 of EN60204-1.

Appendix 6. Compliance to EU EC Directives
[1] Use EN/IEC Standards compliant parts for the circuit breaker and contactor.
[2] Select circuit breaker with instantaneous trip function. (Trip within 30 second when over current of 600%). Apply Annex C of EN60204-1 for sizing of the circuit breaker.
(7) Miscellaneous
[1] Refer to the next section "EMC Installation Guidelines" for methods on complying with the
EMC Directives.
[2] Ground the facility according to each country's requirements.
[3] The control circuit connector ( { ) is safely separated from the main circuit ( ).
[4] Inspect the appearance before installing the unit. Carry out a performance inspection of the final unit, and save the inspection records.
