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 battery+ 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 battery+ 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).

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

draw 7 A, and the second
AA-120 draws 7 A of
additional current from the
batteries.
