Connecting AC Power to the Charger Installing the Charger Connecting AC Power to the Charger Caution: Before connecting AC power to the charger—make sure to set the Voltage Select Switch (SW1) on the charger (Figure 2) to match your AC power source (120 VAC or 240 VAC). Figure 3 shows the voltage selection positions for SW1: Note: The charger is rated for 120 VAC or 240 VAC operation. Therefore, 115V on SW1 indicates 120 VAC operation; and 230V, indicates 240 VAC operation. SW1 set to 1

Installing the Charger Mounting the Charger Mounting the Charger Mounting the Charger into a CAB-X3 Series Cabinet You can mount a charger into the bottom row of a CAB-X3 Series Cabinet, as long as the charger is within 20 feet of the load. Typically, a charger mounts into the lower right corner of the CAB-X3—beside the power supply (Figure 7, position 2). If using an additional CAB-X3, you can mount the charger in the lower left corner (Figure 7, position 2). Figure 7 shows the two mount

Connecting the Charger to a Load Installing the Charger Adding the Charger for Additional Current Due to internal fuses, the maximum alarm current that can be drawn from the batteries and passed through the charger’s two output circuits is limited to 10 amps maximum (each circuit). The PS-12600 batteries, however, are capable of supplying up to 45 amps of current in alarm. The remaining 25 amps of alarm current can be drawn directly from the battery terminals to supply Notification Applia
