2.9 Connecting the Charger to a Load
This section provides three applications for connecting a charger to a load. While
connecting a charger to a load, observe the following precautions:
• Make sure all power has been removed from the charger and the load
• Observe polarity when making connections.
2.9.1 Connecting the Charger to a Single Load
The CHG-75 is designed to provide additional charging capability to an existing FACP
power supply. The charger can be connected to a single power supply as illustrated in
Figure 2.12.
To connect the charger to a single load:
1. Connect the Battery (+) and Battery (-) terminals of the power supply to the
CHG-75 Output Circuit TB2, Terminal 3 (Out +) and Terminal 4 (Out -) as
illustrated in Figure 2.12
2. Connect the batteries to the CHG-75 (refer to Figure 2.10 or Figure 2.11)
