(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 converter unit and servo amplifier (drive unit) must be connected to the corresponding earth
terminals.
(6) Wiring
(a) The cables to be connected to the terminal block of the converter unit and servo amplifier (drive unit)
must have crimping terminals provided with insulating tubes to prevent contact with adjacent terminals.

Insulating tube
Cable
(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 11.1)
(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 11.12 (Section 13.9.5 for 30kW or more).
Use a type B (Note) breaker. When it is not used, provide insulation between the converter unit, servo
amplifier (drive unit) and other device by double insulation or reinforced insulation, or install a
transformer between the main power supply, converter unit and servo amplifier (drive unit).
Note. Type A: AC and pulse detectable
Type B: Both AC and DC detectable
(b) The sizes of the cables described in section 11.8 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
(c) Use the EMC filter for noise reduction.
(8) Performing EMC tests
When EMC tests are run on a machine/device into which the converter unit and servo amplifier (drive unit)
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 converter unit and servo amplifier (drive unit), refer to the
EMC Installation Guidelines(IB(NA)67310).
