CAUTION: Ensure that each power cable lug seats ush against the surface of the
terminal block as you are ghtening the screws. Ensure that each screw is properly
threaded into the terminal. Applying installaon torque to the screw when the
screw is improperly threaded may result in damage to the terminal.
CAUTION: The maximum torque rang 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 ghten 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.
7. Replace the clear plasc cover over the terminals on the faceplate.
8. Aach an electrostac discharge (ESD) grounding strap to your bare wrist, and connect the strap to
an approved site ESD grounding point. See the instrucons for your site.
9. Connect each DC power cable to the appropriate external DC power source.
NOTE: For informaon about connecng to external DC power sources, see the instrucons
for your site.
10. Switch on the external circuit breakers to provide voltage to the DC power source cable leads.
Observe the system LED on front of the router. If the DC power cable is correctly installed and
funconing normally, the system LED lights green steadily. If the system LED is not lit, the power
supply is not funconing normally. Repeat the installaon and cabling procedures.
