Basic Connection Diagram
(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 7) Provide external thermal overload protection for each
when operating frequency is below 30 Hz or when
multiple motors are used.
