Appendix 2. Compliance to EC Directives
A2 - 3
(3) Power supply
[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
[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.

[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.

A2 - 4
(6) Peripheral devices
[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.
