CAUTION: Ensure that each power cable lug seats flush against the surface
of the terminal block as you are tightening the nuts. Ensure that each nut
is properly threaded onto the terminal stud. The nut should be able to spin
freely with your fingers when it is first placed onto the terminal stud.
Applying installation torque to the nut when the nut is improperly threaded
may result in damage to the terminal stud.
CAUTION: The maximum torque rating of the terminal studs on the DC
PDM is 25 lb-in. (33.89 Nm). The terminal studs may be damaged if
excessive torque is applied. Use only a torque-controlled driver or socket
wrench to tighten nuts on the DC PDM terminal studs.
NOTE: For information about connecting to DC power sources, see the

Connect each DC power cable to the appropriate external DC power source.
