A. Locate the MOV assembly. Note wire placement
and remove the 4 wires/lugs from the terminal
block. Remove the screw that secures the MOV to
the chassis. See
Figure 1 .
B. Compare lug styles between the MOV just removed
and the new one.
– If the lugs are identical, install the new MOV in
reverse order. Verify correct wire placement and
tighten the MOV screw to 3.2 N-m (28 lb.-in.).
– If the lugs are different,
cut the lugs off of the new
MOV (as close to the lug
as possible). Strip the
insulation from each lead
approximately 8 mm
(0.31 in.). Crimp the
supplied lugs to the wires.
Install the new MOV in
reverse order. Verify
correct wire placement
and tighten the MOV screw to 3.2 N-m (28 lb.-
in.).
