the connector shell to
ensure proper positioning (see adjacent left side view of D-shell
connector).
4.
Tighten the screws at the top and bottom of the shell, applying a
torque between 1.7 N-m (15 in-lb) and 2.3 N-m (20 in-lb), to securely
attach the cable to the DC power supply module.
5.
To complete the DC connection, secure the other end of each cable wire component of
the DC power cable to the target DC power source.
Check the three individual DC cable wire labels before connecting each cable wire lug
to its power source. One cable wire is labeled
ground
(GND), and the other two are
labeled
positive
