(b) Do not connect two ground cables to the same protective earth (PE) terminal. Always connect cables to
the terminals one-to-one.
PE terminals
PE terminals
(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 cables to be connected to the terminal block of the converter unit, 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 IEC/EN Standard.
The IEC/EN Standard-compliant power connector sets are available as options.
(c) The converter unit and servo amplifier (drive unit) must be installed in the metal cabinet (control box).
(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 type B (Note) breaker. 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 (drive unit).
Note. Type A: AC and pulse detectable
Type B: Both AC and DC detectable
(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 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).
