CAUTION: Ensure that each power cable lug seats flush against the surface of the
terminal block as you are tightening the screws. Ensure that each 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 27.4 lb-in. (3.1 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 27.4 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.
7. Replace the plastic cover over the terminals on the faceplate.
8. Connect each DC power cable to the appropriate external DC power source.
NOTE: For information about connecting to external DC power sources, see the instructions
for your site.
9. Switch on the external circuit breakers to provide voltage to the DC power source cable leads.
10. Repeat Step 2 through Step 9 for the remaining power supply.
11. Observe the LED on the power supply. The LED blinks green as it transitions online. If the power supply
is functioning normally, the LED lights green steadily.
If the LED is red or not lit, the power supply is not functioning normally. Repeat the cabling procedures.
