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.
