GMT Fuse Connections

GMT fuses are only connected to -48VDC if the system has been purchased with the GMT fuse option. This option supplies -48VDC to lugs on the interface card through #6 AWG power cables controlled by a 50 Amp circuit breaker located in circuit breaker Position 1. The 2-hole lugs on both ends of the power cables have #10 holes on 5/8” centers. Connections to the GMT fuses are made at terminal block connectors labeled “F1” through “F8” that are located on the interface card mounted in the top left side of the unit. The connector is sized to accept #12 – #28 AWG wire. Each connector has two positions, labeled “-48V” and “RTN”, for connection of the -48V DC load and load return wires. Refer to Figure 3.8-3for Interface board connections.
