Prepare the Chassis for Module Installation
Before you install the 1757-ABRIO module, you must install and connect a
ProcessLogix or ControlLogix chassis and power supply.
Determine Module Slot Location
Chassis slots are numbered starting from the left, starting at 0. Slot 0 is the
first slot to the right of the power supply.
You can:
• use any size chassis.
• install the module in any available slot.
• install multiple 1757-ABRIO modules in the same chassis, depending
on how your power supply is rated.
Remove and Insertion Under Power
You can install or remove the module while the chassis is powered if you
observe these precautions.
WARNING
When you insert or remove the module while backplane power is on,
an electrical arc can occur. If you connect or disconnect the
communications 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.
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.
