Assembling the I/O Base and the Adapter

Overview

Procedure:

Assembling an

I/O Base and an

Adapter

This section contains safety precautions for handling components and a procedure for assembling 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.

Follow the steps in the table below to assemble an I/O base and an adapter.

Step

Action

1Choose a clean environment to assemble the I/O base and adapter to protect the circuitry from contamination.

2Make sure that the I/O base is not under power when you assemble the module.
