Step Action
3. Attach signal wiring from the fan shelf to the alarm card in the converter shelf immediately
above the fan shelf.
Figure 17 Alarm Wiring for Fan Shelf
4. Attach de-energized DC cabling (typically 14 AWG) as shown here. Use ring lugs or alternate
per local practice. Fuse externally at 5 Amps. Note: Returns for the A and B feeds are shared
on the -48Vdc RTN. The lowest position on the terminal block is to provide frame ground for
the fan shelf. Power feeds should be derived from a fuse or breaker panel using discrete
cabling which is independent from the converter shelf.
