MX28B-1200+27V PRODUCT MANUAL

4.7 Battery connections

Battery connections are made at the top rear of the unit. The +24V and Battery Return buses each provide two sets of 3/8”-16 holes on 1 inch or 1 ¾ inch centers for connecting two-hole battery cable lugs. Refer to Figure 4-4.

A battery disconnect breaker is required external to this equipment. The power plant can monitor auxiliary contacts from this breaker. Battery temperature compensation is available. APC’s master control unit, in conjunction with the optional temperature monitor sensor cable, is used to implement this function.

4.8 +24V DC Distribution

A standard power distribution module can mount up to 38 plug-in circuit breakers providing +24V power for customer loads. Each breaker row is connected at its center to the +24V DC bus, with each column having an ampacity of 300A. Connections for the +24V DC loads are located directly above the corresponding breaker. A typical load connection would utilize a #6 AWG wire with a two-hole lug on 5/8-inch centers, attached with standard #10-32 mounting screws.

The load return cables for each circuit breaker connect to a return bus directly above the top row of circuit breakers. The return bus contains a pattern for 40 two-hole #10-32 lugs on 5/8-inch centers. Figure 4-5 shows the power plant’s DC distribution section.
