Secure the cable lugs to the terminal studs, first with a washer, then with a nut (see
Figure 187 on page 371). Use a 7/16-in. (11 mm) nut driver to tighten the nut. Apply
between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.
CAUTION: You must use an appropriate torque-controlled tool to tighten
the nuts. Applying excessive torque damages the terminal studs and the
power supply. The absolute maximum torque that may be applied to this
nut is 45 lb-in. (5.0 Nm).

access to other hardware components, and that they do not drape where people
could trip on them.
