The following graphic shows you how to assemble the components of the kits for the reversing con-
tactor combination for in frame sizes S10 and S12:
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.
5/6 Mount the reversing contactor
combination to the mounting
plate.
7 First mount the bottom wir-
ing module (7) with the exten-
sion pieces (7.1/7.2/7.3) in
order to connect the main
conducting paths and tighten
down the wiring connections
8 Mount the top wiring module
(8) with the extension pieces
(8.1/8.2/8.3) in order to con-
nect the main conducting
paths and tighten down the
wiring connections
