1. Position the mechanical interlock block and the contactor in the same direction. (The
name plate of the mechanical interlock block should be in the same direction as the
name plate of the contactor.
2. Insert the connection pins of the mechanical interlock block (located on the left and
right sides of the mechanical interlock block) into the pin holes of the forward and
reverse contactors (the forward contactor in the right and the reverse contactor in the
left in the picture). Carefully push the contactors towards the mechanical interlock block
to lock the entire assembly together.
3. Insert the mounting base into the bottom of the mechanical interlock block until it
bottoms. (Make sure that the arrow -shaped protrusion of the mechanical interlock as
far as it will go.
1. To remove the mechanical interlock block, insert a screwdriver into the space
between the mechanical interlock block and the mounting base.
2. Remove the mounting base from the assembly.
3. Gently pull the forward and reverse contactors apart.
1. Position the mechanical interlock and the contactor in the same direction. (The name
plate of the mechanical interlock should be in the same direction as the name plate of the
contactor.)
2. Insert the connection pin of the mechanical interlock into the connection pin hole
located on the right side of the forward contactor. The 7 - shaped hook of the mechanical
interlock reaches the contactor. Position the 7 - shaped hook of the mechanical interlock
to match the ribbed area of the contactor and press the mechanical interlock block
towards the forward contactor.
3. For the reverse contactor, follow the same procedure above, but insert the connection
pin of the mechanical interlock block into the pin hole located on the left side of the
reverse contactor. (Note: The mounting order of the forward or the reverse contactor does
not make a difference in the assembly procedure.)
4. After the mechanical interlock block is installed to both contactors, mount the contac-
tors to the mounting base with the screws (4 screws for each contactor, total of 8 screws.)
Make sure that the mechanical interlock block is completely locked to the contactors.
Please note that there can be operational problems if the mechanical interlock and the
contactors are not properly locked into position.
1. Insert a screwdriver into the 7-shaped hook area between either contactor and the
mechanical interlock and pry out the mechanical interlock.
