Proper DC Cable Routing

Figure 10 shows the proper cable routing for circuit breaker connections. All circuit breaker cables should be routed through the cable openings to the left, when looking at the rear of the shelf, of the connection points. NOTE: Routing the cables in any other manner may harm the personnel or the system.

Circuit 9 contains four circuit breaker and twenty GMT fuse connections. All DC output connections are accessible from the rear (Figure 12), whereas circuit breakers and fuses are accessible from the front (Figure 11).

Make GMT output and return connections by using the compression screws on the GMT terminal strips accessible from the rear (Figure 12). Select wire size according to specifications in the section “DC Output Requirements” on page 10. GMT cables should be routed straight down through the cable holes just below the GMT terminal block. Torque these M3 screws to 4.5 in-lbs. Install fuses into appropriate slots in the GMT fuse block shown in Figure 11. For load output and return circuit breaker connections (positions A and B), connect lugs to the double ¼” -20 studs with 5/8” centers, accessible from the rear, as shown in Figure 12. Circuit breakers can be found behind the distribution door on the right side of the system when viewing it from the front (Figure 11). Size wires and lugs according to specifications in the section “DC Output Requirements” on page 10. Breaker cables should be routed through the cable holes on the left side of the shelf when viewing it from the rear (Figure 10). DO NOT connect an equipment load to LVD-protected output connections.
