ground connection is installed first and disconnected last.
Figure 56. 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).
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 conduct harmful levels of
electricity to persons touching the wires.
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 100mm
(4 in.) apart. Locate the first one within 150mm (6 in.) of the terminal
block.
Note
This system will work with a positive grounded or negative grounded
DC system.
9. Verify that the circuit breaker is in the Off position.
