System Configuration and Wiring
Main Circuits
Always ask to an electric engineer for wiring.
Don't turn on the main power until the wiring and connectings are completed, to avoid electric shocks.
Wiring Instructions
•
Make necessary connections.
For wire diameter, see List of Available Components (page 20).
•
Securely insert connectors.
See the nameplate of the amplifier to check
the power specification.
Install a non-fuse breaker or leakage breaker.
The latter should be a special 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 three-phase 200V,connect L1(10pin), L2(8pin),
and L3(6pin).
For single-phase 100V and 200V, connect
L1(10pin) and L3(6pin).
Connect to the grounding system of the facility.
Never fail to connect between the amplifier's
protective earth terminal ( ) and control
board's protective earth terminal (ground plate)
in order to avoid electric shocks.
Ensure to connect matching in color between
the motor wires and terminals (U, V, W and E).
Don't short circuit or ground. Don't connect to
the main power.
The electromagnetic brake is not polar-sensitive.
For power capacities, see the App. 7.
For use of the brake, see "Holding Brake" in App. 6.
Install a surge absorber.
