2.8.4 Connecting Multiple Power Supplies/Products (Separate
Batteries)
Follow these guidelines when connecting multiple power supplies and products that use batteries
(such as the DS-AMP and DAX):
• Disable Ground Fault detection on all products except one power supply. See Figure 1.1 on
For proper supervision the power supply with the enabled ground fault detection must be
connected to the SLC or to the EIA-485.
• Connect common bond wire between these products.
• All connections must be in conduit and the total battery connection must be less than 20 feet
(6.1 meters) from the enabled power supply.
• Confirm that enabled chargers have the capacity to charge the total load of the selected
battery configuration.
• Connect battery interconnect cables
only after initial system power-up
. Refer to
“Installing and Connecting the Batteries” on page 25.
To determine AMPS-24 battery requirements, refer to Section 4.2 on page 44 in this manual.
Refer to the specific product 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.
