Figure 43. Inserting Wires into a DC Terminal Block
6. Connect the +48 VDC (RTN) feed wire to the terminal block marked
+ (plus).
7. Connect the -48 VDC feed wire to the terminal block marked - (minus).
8. Secure the tray cable near the rack framework using multiple cable
ties to minimize the chance of the connections being disturbed by
casual contact with the wiring. Use at least four cable ties, separated
four inches apart. Locate the first one within six inches of the terminal
block.
9. Ensure that the circuit breaker is in the OFF position.
10. Connect the supply-cable wires to the circuit breaker.
11. Energize the circuit breaker.
12. Turn the power switch to the ON position.
If you installed an optional redundant power supply, repeat this procedure
to attach DC wires to the second terminal block.

Warning: Check to see if there are any exposed copper strands
coming from the installed wires. When this installation is done
correctly there should be no exposed copper wire strands
extending from the terminal block. Any exposed wiring can con-
duct harmful levels of electricity to persons touching the wires.
