2.4.4 Connecting Multiple Power Supplies (Separate Batteries)
This application may be used when you want a single power supply to monitor for ground fault for
multiple power supplies. Follow these guidelines when connecting multiple power supplies:
• Disable Ground Fault detection at all power supplies except one. 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.
• Connect common bond wire between the main power supply and power supplies with
disabled ground fault detection.
• Connect battery interconnect cables
only after initial system power-up
. Refer to
“Installing and Connecting the Batteries” on page 20.
To determine ACPS-610 battery requirements, refer to Section 5.2 on page 49 in this manual.
Refer to the specific power supply manual(s) and/or Device Compatibility Document for further
information and instructions.
Figure 2.13 Connecting Multiple Power Supplies with Common Bond Wire
NOTE:
For best results, enable ground fault detection on the power supply connected to the
battery with the largest capacity.
!
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.
