4.3.1 Overview
The control module in a standard conguration contains two ECMs, one dry
contact card, and one monitoring interface card from left to right. The four cards
are hot-swappable. One subrack is reserved above the dry contact card. A
backfeed protection card or dry contact extended card can be inserted into the
subrack.

4.3.2 ECM
● As a control interface for the entire system, the ECM communicates with each
module and provides a bus for communication between the dry contact card
and the system control card. The ECM ensures equalized output currents
between modules so that load power is equally shared.
