2-6 Install Your Adapter
Install the I/O Modules After installing and wiring the adapter, install the POINT I/O modules
used for your application.
For more information on installing and wiring the multiple POINT I/O
modules, see the:
• installation instructions for each catalog number
• POINT I/O digital and analog modules user manual in
publication 1734-UM001
• the list of publications in the Preface as a guide
Replace an Adapter To replace an adapter in an existing system, proceed as follows.
IMPORTANT
Do not leave any empty slots when installing a
POINT I/O system with the 1734-ACNR adapter.
ATTENTION
You must use Series C POINT I/O modules
with the 1734-ACNR module. Series A and B
POINT I/O modules will not work with the
1734-ACNR adapter.
ATTENTION
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.
