Step 7
Tighten the KEP-style hex nut screws (use the screwdriver to tighten the ground screw in the terminal
block to a torque of 18-22 in-lbs) on the power supply studs
Step 8
Insert the positive ground cable. Replace the ground lug with cable in the following order:
a.
Flat Washer
b.
Ground lug with positive wire
c.
Kepnut screw
Step 9
Tighten the KEP-style hex nut screws (use the screwdriver to tighten the positive ground screw in the
terminal block to a torque of 18-22 in-lbs) on the power supply ground studs and repeat the same steps
for the negative ground stud and wire (see
Figure 14-52
).
Note
Secure the wires coming in from the terminal block so that they cannot be disturbed by casual contact.
Step 10
Use tie wraps to secure the wires, so that the wires are not pulled from the terminal block by casual
contact. Tie-wrap studs are located below the power supply terminal block.
Note
The ground wire must contain a loop when securing it to the tie-wrap tab to prevent it from being
pulled out.
Step 11
Replace the terminal block plastic cover and tighten the screws. The plastic cover slides in easily over
the terminal block.
Step 12
If you taped the circuit breaker, then remove the tape from the circuit-breaker switch handle and move
the circuit-breaker handle to the on position.
Step 13
Switch the power supply circuit breaker switch to the On (|) position.
This completes the procedure for connecting the DC power supply in the Cisco ASR 1004 Router.
