Mechanical interlock
installation
The following graphics show you how to install the front mount mechanical
interlock for frame size S0:
Drawing: Frame size S0 Step Procedure
1 Attach both of the wiring modules in
order to connect the main conducting
paths. Shown as the circled numbers:
c = Top wiring module
d = Bottom wiring module
2 Push the sliding switch on the upper
portion of the mechanical interlock to
RESET, in order to be sure of the condi-
tional state of the module.
3/4/5 First attach the mechanical interlock in
the contact opening of the left contac-
tor (3), then with a swinging motion
attach the mechanical interlock in con-
tact opening of the right contactor (4)
and pull the interlock downward until it
sits securely in place (5).
6 In the proper operational condition, the
upper sliding switch on the front side
of the mechanical interlock is to the left
and the lower sliding switch is to the
right.
