APPENDIX
(5) Grounding
(a) To prevent an electric shock, the protective earth (PE) terminal (marked ) of the servo amplifier must
be connected to the protective earth (PE) of the cabinet.
(b) Do not connect two ground cables to the same protective earth (PE) terminal. Always connect cables to
the terminals one-to-one.
PE Terminal
PE Terminal
(c) If an earth leakage circuit breaker is used, always earth the protective earth (PE) terminal of the servo
amplifier to prevent an electric shock.
(6) Wiring
(a) The wires 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.
Crimp terminal
Insulating tube
Wire
(b) Use the servo motor-side power connector which complies with the IEC/EN Standard.
The IEC/EN Standard-compliant power connector sets are available from us as options.
(c) The servo amplifier must be installed in the metal cabinet.
(7) Peripheral devices, options
(a) Use the circuit breaker and magnetic contactor models which are IEC/EN Standard-compliant products
given in this Instruction Manual.
Use a residual current device (RCD) of type B. When it is not used, provide insulation between the
servo amplifier and other device by double insulation or reinforced insulation, or install a transformer
between the main power supply and servo amplifier.
(b) The sizes of the wires given in this Instruction Manual meet the following conditions. For use in any
other conditions, follow Table 5 and Annex C of IEC/EN 60204-1.
Ambient temperature: 40 (104 )
Sheath
: PVC (polyvinyl chloride)
Installation on wall surface or open cable 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).
