Procedures
1. Check the contents of shipping box. Reference
Unpack the shipping box making sure that the contents include:
•
Analog I/O module (Catalog Number 1746-Series)
•
installation instructions (publication 1746-IN008)
If the contents are incomplete, call your local Allen–Bradley representative for assistance.
2. Determine your power requirements for the modular controller. Reference
Review the power requirements of your system to see that your chassis supports placement of the
analog module.
•
For modular style systems, calculate the total load on the system power supply using the
procedure described in the SLC 500 Modular Hardware Style User Manual (publication
1747-UM011) or the SLC 500 Family System Overview (publication 1747-SO001).
•
For fixed SLC 500 controllers, refer to the SLC 500 Fixed Hardware Style Installation &
Operation Manual (publication 1747-6.21).
