System Configuration and Wiring

Main Circuits

Don't turn on the main power until the wiring is completed, to avoid electric shocks.
Wiring Instructions
A Detach the terminal block by removing the cover securing screw.
B Make necessary connections.
Use clamp terminal connectors with an insulation cover. For wire diameter and connector sizes, see List of
Available Components (page 20).
C Attach the terminal block cover and tighten the cover securing screw.

See the nameplate of the driver to check the power specification.
Install a non-fuse breaker or leakage breaker. The latter should be a spe-
cial one intended for inverters, i.e. with a countermeasure against higher
harmonics.
Install a noise filter without fail.
Install a surge absorber to the magnetic contactor coil.
Install an AC reactor.
For single-phase 100V, connect between L1 and r, and
between L3 and t. Do not use L2 terminal.
Don' t remove the short bar connecting between B1 and B2. Remove this only when
an external regenerative discharge resistor is connected.
Ensure matching in color between the motor wires and
terminals (U, V and W).
Don't short circuit or ground. Don't connect to the main
power.
If cannon plugs are used, see the next page.
Connect to the grounding system of the facility.
Never fail to connect between the driver's protective earth ter-
minal ( ) and control board's protective earth terminal (PE)
in order to avoid electric shocks.
No multiple connections to a single earth terminal permis-
sible. There are two earth terminals (
Earth wires should in no case be connected or made contact to any of the terminals
other than the earth terminals on the block.
The electromagnetic brake is not polar-sensitive.
For power capacities, see the Appendix (page 11).
For use of the brake, see "Holding Brake" in page 9 of Appendix.
