CHG-120   Instruction   11/22/04   PN: 52459:A   FCI P/N:9000-0572

Connecting the Charger to a Load

This section provides two applications for connecting a charger to a load. While connecting 
a charger to a load, observe the following precautions:

Make sure all power sources are off to the charger and the load.

Follow polarity when making connections.

Connecting the Charger to a Multiple Load  

You can connect a charger to multiple 

loads, such as a main power supply, auxiliary power supply, amplifiers, and so forth, as 
shown in Figure 9.

Figure 9 Typical Wiring for a Charger to a Multiple Load

To connect a charger as shown in Figure 9, follow these steps:

Step Action

1

Connect the 

 and 

battery–

 terminals of the power supply to the charger 

output circuit (TB2: Out 1+ and Out 1–) as shown in Figure 9.

2

Connect the 

 and 

battery–

 terminals of the amplifier to the charger 

output circuit (TB2: Out 2+ and Out 2–) as shown in Figure 9.

3

Connect the batteries to the charger (for battery connections see Figure 5 or 
Figure 6).

Generic Audio 

Amplifier

Power Supply

Note:

 Figure 10 shows a 

wiring diagram for tying the 
load to battery terminals to 
obtain additional current. For 
example, the first AA-120 
draws 7 A, the daisy-chained 
Generic Audio Amplifiers 
draw 7 A, and the second 
AA-120 draws 7 A of 
additional current from the 
batteries.
