The following graphic shows you how to assemble the components of the kits for the reversing con-
tactor combination for in frame size S6:
Drawing: Frame size S6 Step Procedure
1/2 Remove the covers that block
the opening for mechanical
interlock on both contactors.
3/4 Insert the mechanical inter-
lock into the left and right
openings respectively in order
to mechanically interlock the
contactors.
5 Plug-in both of the connection
clips to the backside of the
contactor.
6/7 Mount the reversing contactor
combination to the mounting
plate.
8/9 Attach both of the wiring
modules (8) in order to con-
nect the main conducting
paths and tighten down the
wiring connections (9).
