The following table shows you the components of the kit for the contactor
combination for reversing in frame size S0 and explains how to put it
together:
Drawing: frame size S0 Step Procedure
1/2 Mount the mechanical inter-
lock between the two contac-
tors.
3 Wire the actuating voltage and
the electrical reversing inter-
lock using the auxiliary con-
ducting paths.
4/5 Attach the wiring modules in
order to connect the main con-
ducting paths and tighten the
terminals.
