10 POINT I/O DeviceNet Adapter
Publication 1734-IN026A-EN-P - April 2005
Install a Replacement Adapter in an Existing System
Your existing control application may be using another DeviceNet
adapter (for example, 1734-PDN) that you want to replace with a
1734-ADN(X) DeviceNet adapter. Remove the existing adapter from
the DIN rail as follows.
1. Remove power to the adapter and all I/O modules in your
existing system.
2. Remove the wiring assembly and DeviceNet cable from your
existing adapter.
3. Remove the adjacent I/O module.
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.
WARNING
When you connect or disconnect the Removable
Terminal Block (RTB) with field-side power
applied, 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.
