Figure 3 - Typical DC Common Bus System Installation
In the example above, the leader IAM module is connected to the follower IAM
module via the DC common-bus. When planning your panel layout, you must
calculate the total bus capacitance of your DC common-bus system to be sure
that the leader IAM module is sized sufficiently to pre-charge the entire system.
Refer to Appendix
D, beginning on page 245, for more information.

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