FLEX 5000 Terminal Base Assembly Modules
Dimensions (with Shield Bar installed)
Ground Considerations
You must ground DIN rails according to the Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1
.
System Power Considerations
FLEX 5000 EtherNet/IP adapters provide power to a FLEX 5000 I/O system via a Power RTB that is connected to an external power supply and
installed on the adapter.
The Power RTB provides module power to the system. Module power refers to system-side power that is used to operate the FLEX 5000 I/O
system. Module power is provided through the Power RTB and passed across the module power bus.
• You must limit the SA field-side power source to
10 A, max, at 18...32V DC
.
• Confirm that the external module power supply is adequately sized for the total module power bus current draw in the system.
For example, if the total module power current draw, including current inrush requirements, is 5 A, you can use a module power supply that
is limited to 5 A.
• You must use SELV-listed power supplies for module power if there are Functional Safety modules that are connected to the
FLEX 5000 I/O system.
• Not all power supplies are certified for use in all applications, for example, nonhazardous and hazardous environments.

Additional Resources on page 15
Tools
The following tools are needed:
• screw driver such as the 1492-N90 terminal block screw driver with hardened 3mm diameter blade
• Wire stripper
• Wires
For more information on available wire sizes and wire insulation stripping length, see
Terminal Base Assembly Specifications on page 14
.
ATTENTION:
This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use
of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately. Be sure to ground the DIN rail properly. Refer to
Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication
1770-4.1
for more information.
ATTENTION:
Power to this equipment and all connected I/O must be supplied from a source compliant with the following:
Isolated from Mains power via an approved Isolating Transformer constructed with Basic Insulation
IMPORTANT
We recommend that you use separate external power supplies for the adapter and the adjacent terminal base. This practice can prevent unintended
consequences that can result if you use one supply.
