Wiring of the Main Circuit (A to D-frame)

•Wiring should be performed by a specialist or an authorized personnel.

•Do not turn on the power until the wiring is completed.

Tips on Wiring

1) Peel off the insulation cover of the cable. (Observe the dimension as the right fig. shows.)

2)Insert the cable to the connector detached from the driver. (See P.37 for details.)

3)Connect the wired connector to the driver.
