Typical DC Common Bus System Installation
In the example above, a leader IAM is connected to a follower IAM via the dc
common bus. When planning your panel layout, you must calculate the total
bus capacitance of your dc common bus system to correctly size the leader
IAM to pre-charge the entire system. In RSLogix5000 software you identify
the common bus follower (disabling its shunt capabilities), and in doing so
require the leader IAM to control the entire common dc bus.
Refer to Appendix D, beginning on page 209, for more information.

IMPORTANT
If total bus capacitance of your system exceeds the leader IAM
pre-charge rating and input power is applied, the IAM seven-segment
Fault Status LED indicator will display error code E90 (pre-charge
timeout fault). To correct this condition, you must replace the leader
IAM with a larger module or decrease the total bus capacitance by
removing axis modules.
