Overview
Recently revised to meet new Interbus standards for electrical noise immunity, select Momentum products have been updated with an additional ground screw. This second ground screw is being added to all new and upgraded Momentum products. Currently, four communication adapters have been updated. They are:
Momentum Interbus Communication Adapter (170 INT 110 03), which supports the diagnostic functions of a Generation 4 Interbus Master and is compliant with Interbus certification, version 2
Momentum Ethernet Communication Adapter (170 ENT 110 01), version 2
Momentum Ethernet Communication Adapter (170 ENT 110 02), version 1
Momentum FIP IO Communication Adapter (170 FNT 110 01), version 2
These communication adapters contain a new grounding system, which was originally required to meet the revised Interbus electrical noise immunity standard (ability to pass a 2.2kv electrical fast transient burst test). This grounding system includes a male-female standoff and screw in the communication adapter, which is connected to a fixed standoff-ground nut on the printed circuit board on selected Momentum I/O modules.
Momentum I/O Modules
The Momentum I/O modules include the fixed standoff-ground nut assembly. The male-female standoff and ground screws are found in the redesigned communication adapters.

Required Tools
The only tool required to install the ground screw is a PZ 2 Phillips head screwdriver. The recommended maximum torque on the ground screw is 0.5 Nm (4.4 in/lb).
Installation
| CAUTION | |
|---|---|
POTENTIAL MODULE DAMAGE When using the new version of the above I/O modules with
any communication or processor adapter that does not have the second
ground screw feature, do not install the standoff into the fixed standoff-ground
nut assembly on the I/O module’s printed circuit board. The
standoff could touch some of the components on the adapter, which
may cause faulty operation or product failure. Failure to follow these instructions can result in injury or equipment damage. | |
To install the ground screw, follow the steps below. Refer to the figure below for the screw locations.
Step |
Action |
|---|---|
1 |
Install the standoff into the threaded fixed standoff-ground nut assembly, which is located on the I/O module’s printed circuit board. |
2 |
Snap the communication adapter onto the I/O module. Follow the same procedure as all other Momentum products. (For more information on communication adapter assembly, refer to the Modicon Momentum I/O Base User Guide (870 USE 002). |
3 |
Install the ground screw through the top of the communication adapter. |

Backward Compatibility
The above I/O modules can also be used with any of the Momentum communication or processor adapters that do not include the ground screw.
