Install The Module - Rockwell Automation Allen-Bradley 1756-EN2TSC Installation Instructions Manual

Install the Module

You can install or remove a module while chassis power is on. To install the module, follow these steps.
Table 6 - Removal and Insertion Under Power
WARNING: When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on
both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.
Table 7 - Multi-point Network Communication
WARNING: If you connect or disconnect the communication cable with power applied to this module or any device on the network, an
electrical arc can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
1. Determine module slot location.
2. Install the communication module in any slot in a ControlLogix® or ControlLogix-XT™ chassis.
You can install multiple communication modules in the same chassis.
This example shows chassis slot numbering in a 4-slot ControlLogix chassis. Slot 0 is the first slot and is always the left-most slot in
the chassis.
WARNING: When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on
both the module and its mating connector. Worn contacts can create electrical resistance that can affect module operation.
ATTENTION: Use caution when handling the module. One side of the module is a heat sink and can be hot.
