Install Your I/O Modules and Attach Your Power Supply

Use the installation instructions/user manuals for your modules to install them
into the chassis. Use the installation instructions for your power supply
(1746-P1, -P2, -P3, -P4, or -P5) to attach it to your chassis.
ATTENTION:
Important: Series B chassis have a 1MΩ resistor between logic ground and
chassis ground. When using a 1746-P3 dc power supply, follow the grounding
instructions provided with the power supply to avoid unwanted potentials across
the logic ground of the SLC processor.
