touching a grounded object.
• Avoid touching connector terminations and circuit components.
• Keep the module in its electrostatic shielded bag when not in use.
1. Unpack the module.
Unpack the module making sure that the contents include these
items:
• Module (Catalog Number 1746-INT4)
• Removable terminal block (factory-installed on module) with
CJC sensors attached
If the contents are incomplete, call your local Rockwell
Automation representative for assistance.
2. Review the power requirements of the modules drawing power
from the chassis power supply.
• The fixed, two-slot chassis supports two 1746-INT4 modules.
If combining a 1746-INT4 module with a different type of
module, refer to Considerations for a Fixed Controller in
Chapter 3.
• For a modular system, compute the total load on the system
power supply.
Refer to the procedure described in the SLC 500 Modular
Hardware Style User Manual, publication 1747-UM011, or the
SLC 500 Systems Selection Guide, publication 1747-SG001.
