Mounting and Wiring the Shunt Trip
4. Remove the shunt trip and white disk from the A-
mech and install the pin and clamp into the
marked hole. Keep in mind the linkage should be
between the white disk and A-mech when re-
installed and the clamp should be on the outside
face of the white disk as shown in figure 8.
5. Re-install the shunt trip permanently onto the A-
mech with the two sets of bolts, lock washers,
and nuts using a 10 mm socket. Slide the white
disk back onto the half-moon shaft and secure
with a cir-clip as shown in figure 9.
6. The shunt trip features a pull-apart wiring termi-
nal that can be separated by a small flat head
screw driver. Gently pry the white plastic hous-
ing away from the female housing, figure 10, to
which the coil wires are attached. The plug can
be wired separate from the coil and plugged back
in to complete the circuit.
