screw is properly threaded into the terminal. Applying installation torque
to the screw when improperly threaded may result in damage to the
terminal.
CAUTION: The maximum torque rating of the terminal screws on the DC
power supply is 9 lb-in. (1.02 Nm). The terminal screws may be damaged
if excessive torque is applied. Use only a torque-controlled driver to tighten
screws on the DC power supply terminals. Use an appropriately sized
driver, with a maximum torque capacity of 9 lb-in. or less. Ensure that the
driver is undamaged and properly calibrated and that you have been
trained in its use. You may wish to use a driver that is designed to prevent
overtorque when the preset torque level is achieved.
Replace the clear plastic cover over the terminals on the faceplate.
