Description
The Allen-Bradley 1746-N2 is a slot filler module designed specifically for the SLC 500 modular hardware platform. This physical barrier accessory occupies empty or unused I/O slots within an SLC 500 chassis to help maintain system integrity. By physically blocking open slots, the module prevents dust, dirt, and foreign debris from entering the chassis and potentially damaging sensitive backplane pins or circuitry.
Constructed to fit standard SLC 500 chassis backplane guides, the 1746-N2 installs easily without requiring specialized tools or wiring. It provides an economical way to keep control enclosures clean and organized while protecting unpopulated backplane connectors from environmental contaminants in industrial control panel installations.

Installation Guidelines
Ensure the industrial enclosure power is turned off before servicing or installing components in the rack. Align the 1746-N2 slot filler module with the top and bottom card guides of the desired empty slot in the SLC 500 chassis. Push the module firmly straight back along the guides until it is fully seated against the backplane. Secure any chassis-specific locking mechanisms if applicable.
