CAUTION
Risk of damage to power connections
The metal of the top stud of each pair is softer than the
bottom lug because of increased electrical conductivity.
Ensure that you do not overtighten either stud, nor leave
one too loose. Damaging a stud can mean the BIP must be
replaced.
16 Tighten each stud nut to 6.5 Nm (57.5 in.-lbs) using a properly calibrated
torque wrench with the measurement near the middle of wrench's range.
17 Slide the insulating boot to the BIP end of the cable, and align it with the
shape of the lug (toe upwards). Rest the boot flush against the rear of the
BIP.
18 Fasten the boot retainer clamp over the stud.
19 For each remaining power cable, working from right to left, repeat step 9
to step 18 for the 7 remaining cables.
20 Fasten the strain-relief bar back onto the frame uprights.
21 Use tie-wraps to fasten the black-and-white and red cables along the
underside of the strain-relief bar and to the lower half.
