Install the XM-124 Standard Dynamic Measurement Module Chapter 1
Power Requirements
Before you install the module, calculate the power requirements of all modules
that are interconnected via their side connectors. The total current draw
through the side connector cannot exceed 3 A. See the specifications for the
individual module for power requirements.
