(5) Grounding
(a) To prevent an electric shock, always connect the protective earth (PE) terminals (marked
) of the
servo amplifier to the protective earth (PE) of the control box. Connect PE terminal of the control
box to the NEUTRAL of a power supply. Be sure to ground the NEUTRAL of a power supply.
(b) Do not connect two ground cables to the same protective earth (PE) terminal. Always connect the
cables to the terminals one-to-one.
PE terminals PE terminals
(c) If a leakage current breaker is used to prevent an electric shock, the protective earth (PE) terminals
of the servo amplifier must be connected to the corresponding earth terminals.
(6) Wiring
(a) The cables to be connected to the terminal block of the servo amplifier must have crimping
terminals provided with insulating tubes to prevent contact with adjacent terminals.

(b) Use the servo motor side power connector which complies with the EN Standard. The EN
Standard-compliant power connector sets are available from us as options. (Refer to Section 13.1.2)
(7) Auxiliary equipment and options
(a) The no-fuse breaker and magnetic contactor used should be the EN or IEC standard-compliant
products of the models described in Section 13.2.2.
(b) The sizes of the cables described in Section 13.2.1 meet the following requirements. To meet the
other requirements, follow Table 5 and Appendix C in EN60204-1.
Ambient temperature: 40 (104) [ ( )]
Sheath: PVC (polyvinyl chloride)
Installed on wall surface or open table tray
(c) Use the EMC filter for noise reduction.
(8) Performing EMC tests
When EMC tests are run on a machine/device into which the servo amplifier has been installed, it
must conform to the electromagnetic compatibility (immunity/emission) standards after it has
satisfied the operating environment/electrical equipment specifications.
For the other EMC directive guidelines on the servo amplifier, refer to the EMC Installation
Guidelines(IB(NA)67310).
