Typical DC Common Bus System Installation
In the example above, the leader IAM is connected to the 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 ensure that the leader IAM is sized sufficiently to pre-charge
the entire system.
Refer to Appendix D, beginning on page 231, 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 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.
