A2 - 3
(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.

(5) Wiring
[1] Always use crimp terminals with insulation tubes so that the connected wire does not contact
the neighboring terminals.

(6) Selecting the wire size for EC Directive compliance
To comply with the EC Directives, select the wire size from the following table using each drive
unit's capacity as a reference.
The wire types are as follow.
PVC : Polyvinyl chloride
EPR : Ethylene polypropylene
SIR : Silicon rubber

* The wire sizes in the above table comply with EN60204 under the following conditions.
• Ambient temperature 40°C
• Wire laid along wall or in open cable tray
When using under other conditions, refer to EN60204 Appendix 5 and Appended Material C.

(7) Peripheral devices
[1] Use EN/IEC Standards compliant parts for the no-fuse breaker and contactor.
(8) Miscellaneous
[1] Refer to "MDS-C1 INSTRUCTION MANUAL" 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.
