The following table shows you the components of the kits for the contactor
combination for reversing in frame size S2 and S3 and explains how to put it
together:
Drawing: frame size S2 (S3) Step Procedure
1/2/3 Mount the mechanical inter-
lock between the two contac-
tors. Then insert the 2
connecting clips (10 mm spac-
ing) on the back of the two
contactors.
4 Wire the actuating voltage and
the electrical reversing inter-
lock using the auxiliary con-
ducting paths.
5/6 Attach the wiring modules (5)
in order to connect the main
conducting paths and tighten
the terminals (6).
