(5) Grounding
1) 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.
2) Do not connect two ground cables to the same protective earth (PE) terminal as shown at
right below. Always connect the cables to the terminals one-to-one.
3) 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
1) 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.
2) When the servo motor has a power supply lead, use a fixed terminal block to connect it with
the servo amplifier. Do not connect cables directly.
3) 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.
(7) Auxiliary equipment and options
1) The no-fuse breaker and magnetic contactor used should be the EN or IEC Standard-compli-
ant products of the models described in Section 6-2-1.
2) The sizes of the cables described in Section 6-2-2 meet the following requirements. To meet
the other requirements, follow Table 5 and Appendix C in EN60204-1.
• Ambient temperature: 40 (104) [°C(°F)]
• Sheath: PVC (polyvinyl chloride)
• Installed on wall surface or open table tray
3) Use the EMC filter for noise reduction. The radio noise filter (FR-BIF) is not needed.
(8) Servo motor
For outline dimension drawings not shown, contact Mitsubishi.
(9) 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 INSTALLA-
TION GUIDELINES (IB(NA)67310)".
