MX28B600-48V

a 50 A. circuit breaker located in circuit breaker Position 1. The interface card provides fuseholders for eight fuses, labeled “F1” through “F8”, which can be used for small -48V DC loads. The maximum fuse size that should be used is 10A.

5.7.3 Load Connections

5.7.3.1 Circuit Breakers

Connections for -48V DC loads require standard two-hole lugs for #10 screws on 5/8” centers and are located directly above the corresponding circuit breaker. The load returns connect to the respective return bus located just above and rearward of the breaker connection points. The upper tier is seen in Figure 4.7-1.The return buses provide a total of 40 sets of threaded #10-32 holes on 5/8” centers and four sets of threaded ¼”-20 holes on ¾” centers for connection of two- hole lugs on load return wires.

5.7.3.2 Optional GMT Fuses

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. Each connector has two positions, labeled “-48V” and “RTN”, for connection of the -48V DC load and load return wires.

5.8Battery Temperature Probe Installation

The optional temperature probe is used to monitor the battery string temperature. To get the most representative temperature measurement, the probe should be placed in contact with a battery cell that is centrally located. The probe should be placed directly in contact with the cell (not the frame surrounding the cell). Generally, the cell cover can be used; be careful not to allow the probe body to touch the terminals.

1) Plug the connector end of the temperature probe into J5 the control unit backplane card.

2)Route the cable as required to position the probe on the selected battery cell

3)Remove the adhesive protection strip from the probe body and press the adhesive side of the probe on the battery cell cover.

5.9Power-Up and Checkout

Before initiating power-up and checkout, ensure that the following conditions exist:

1)Make sure that the external circuit breaker protecting the cables from the battery to the power plant is turned OFF (the battery cables should be connected to the power plant, but the battery should not be connected).

2)Make sure that all load circuit breakers are turned OFF (including the one feeding the GMT fuses if the unit has the GMT fuse option).

3)Verify that all rectifiers have been installed.
