(Note 4) Refer to the figure at right for the power ON and
Run command ON timing. Even if the main circuit
power and operation command are turned ON
simultaneously, the control power will not be turned
ON for 2.0 seconds and not permit operation.
(Note 5) When the contactor is to be opened and closed for
each operation, be sure to insert an ACL on the primary
side of the contactor to reduce the inrush current.
(Note 6) When a DC reactor is used, remove the shorting
bar between terminals P and P1.

(Note 1) Do not start and stop the motor with only the MC
switch.
Refer to p.23 for the reference circuit for MC.
(Note 2) Be sure to ground the inverter chassis and motor.
(Note 3) The common of each terminals differ.
