Installing and Connecting the Batteries
2.8.5 Connecting Multiple Power Supplies/Products (One Set of
Batteries)
Certain system designs may require connecting multiple power supplies and products that use
batteries (such as the DS-AMP and DAX) to one set of batteries. Follow these connection
guidelines:
• For proper supervision, enable only the charger directly connected to the batteries. Disable
all other chargers.
• Confirm that the enabled charger has the capacity to charge the total load of the selected
battery configuration.
• Use PK-PPS to set the charger to the appropriate battery charger current for the system's
battery capacity.
• Disable Ground Fault detection on all power supplies/products except the one that is
charging the batteries. See Figure 1.1 on page 11.
For proper supervision the power supply with the enabled ground fault detection must be
connected to the SLC, or to the EIA-485 to the CPU2-3030, NCA-2 or DS-DB.
• All power supply to power supply connections must be in conduit and the total battery
connection must be less than 20 feet (6.1 meters).
• Connect battery interconnect cables only after initial system power-up. Refer to
"Installing and Connecting the Batteries" on page 25.
To determine battery requirements, refer to Section 4.2, "Calculating the Battery Requirements" in
this manual.
Refer to the specific power supply manual(s) and/or Device Compatibility Document for further
information and instructions.
CAUTION: Risk of possible equipment damage.
!
To maintain proper supervision, auxiliary supplies used to power Panel Circuits, such as the
ICM-4/E, must be connected to the same batteries as the main power supply. Failure to do so
may result in equipment damage.
