Assembling an Adapter and an I/O Base
Original instructions
About us
Overview
A processor adapter or communication adapter can be snapped directly onto a Momentum I/O base. This section contains safety precautions for handling components and an assembly procedure.
Connection Points
The adapter and I/O base connect at these three points.
No Tools Required
NOTICE
STATIC ELECTRICITY DAMAGE
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 follow these instructions can result in equipment damage.
DANGER
RISK OF ELECTRICAL SHOCK
Make sure that the I/O base is not under power when it does not have an adapter mounted on it. Electrical circuitry on the I/O base may be exposed when a Momentum adapter is not mounted.
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 follow these instructions will result in death or serious injury.
The components can be snapped together by hand. No assembly tools are required.
Procedure
Follow the steps in the table below to assemble an adapter and an I/O base.
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 while you assemble the module.
3
Align the two plastic snap extensions on the adapter with the slots on the sides of the I/O base. The 12-pin ATI connectors will automatically line up when the units are in this position. The two devices should be oriented such that their communication ports are facing out on the back side of the assembly.
4
Push the adapter onto the base, gently pressing the locking tabs inward.
Result: The locking tabs on each side of the adapter slide inside the I/O base and out through the locking slot. The 12-pin ATI connectors on the two units are mated to each other in the process.
Next Step
Once the adapter and I/O base have been assembled, the device can be mounted on a DIN rail or surface-mounted inside a panel enclosure.
A Momentum device is classified as open equipment; i.e., electrical circuitry on the unit may be exposed. Open equipment should be installed in an industry-standard enclosure, and direct access must be restricted to qualified service personnel.
