8. Connect Input Power and Frame Ground
Notes:
1. Each feed supplies half of the shelf. A&B feeds for side 1 and A&B feeds for side 2.
2. Power feeds should be derived from a fuse or breaker panel using discrete cabling which is
independent from the converter shelf.
3. Fuse externally at 10 Amps.
4. Use ring lugs or alternate per local practice.
5. Returns for the A and B feeds are shared on the -48Vdc RTN.
6. The right position on the terminal block is the frame ground for the Fan Shelf.
7. Connect de-energized DC cabling (typically 16 AWG) as shown here.
8. Connect Frame Ground wire.
