ACB Interlock
Identify the ‘ groove ’, ‘ wire fixing nut ’, ‘ wire fixing bolt ’, ‘ lever ’ and ‘ wire insertion hole ’ on the mechanical
interlock mechanism (see below).
11. Loosen the ACB 1 port D wire fixing
nut so that the wire insertion hole is
exposed. Attach the ‘fixed’ cable end to
ACB 1 port ’D’ on the mechanical
interlock mechanism with the jig fitted
as shown below.
12. With the ‘fixed’ cable end slotted into ACB 1 port ‘D’, adjust the top
and bottom cable fixing nuts ’up’ until it clamps the cable end to the
support (see left). It is important that the ’top’ cable fixing nut is near
its maximum end. Keep finger tight at this stage.
13. Push the inner core through the wire
insertion hole. Ensure the inner core
follows the ’groove’. The inner core should
not extend past the ’grove end’. Tighten
the wire fixing nut to 4.7 — 5.9Nm with
10mm torque wrench. Repeat steps 11- 13
for ACB 2.
