Overview This section contains safety precautions for handling components and a procedure
for assembling an I/O base and an adapter.
Procedure:
Assembling an
I/O Base and an
Adapter Follow the steps in the table below to assemble an I/O base and an adapter.
CAUTION
ADAPTER MAY BE DAMAGED BY STATIC ELECTRICITY
Use proper ESD procedures when handling the adapter, and do not
touch the internal elements. The adapter’s electrical elements are
sensitive to static electricity.
Failure to observe this precaution can result in injury or
equipment damage.
CAUTION
ELECTRICAL CIRCUITRY MAY BE EXPOSED
Electrical circuitry on the I/O base may be exposed when a Momentum
adapter is not mounted. Make sure that the I/O base is not under power
when it does not have an adapter mounted on it. To make sure that
power is not present, do not insert the wiring connectors to the I/O base
until after the adapter has been mounted.
Failure to observe this precaution can result in injury or
equipment damage.
Step Action
1 Choose a clean environment to assemble the I/O base and adapter to protect the
circuitry from contamination.
2 Make sure that the I/O base is not under power when you assemble the module.
