The main features of the terminal blocks are:
oTool-free wiring with spring clamp push-in technology
oSimple push-button wire release
oAbility to label each terminal
oPlain text labeling also possible
oTest access for standard probes
oCan be custom-coded

A slice must only be composed of a single color. For example, a gray bus base should only be assembled with a gray electronic module and a gray terminal block. However, color alone is not sufficient for compatibility; always confirm that functionality of slice components matches as well.
|
|
|
INCOMPATIBLE COMPONENTS CAUSE ELECTRIC SHOCK OR ARC FLASH |
|
oDo not associate components of a slice that have different colors. oAlways confirm the compatibility of slice components and modules before installation using the association table in this manual. oVerify that correct terminal blocks (minimally, matching colors and correct number of terminals) are installed on the appropriate electronic modules. |
|
Failure to follow these instructions will result in death or serious injury. |
|
|
|
FIRE HAZARD |
|
oUse only the correct wire sizes for the current capacity of the I/O channels and power supplies. oFor relay output (2 A) wiring, use conductors of at least 0.5 mm2 (AWG 20) with a temperature rating of at least 80 °C (176 °F). oFor common conductors of relay output wiring (7 A), or relay output wiring greater than 2 A, use conductors of at least 1.0 mm2 (AWG 16) with a temperature rating of at least 80 °C (176 °F). |
|
Failure to follow these instructions will result in death or serious injury. |
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
Do not exceed any of the rated values specified in the environmental and electrical characteristics tables. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
Do not connect wires to unused terminals and/or terminals indicated as “No Connection (N.C.)”. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |

Failure to follow these instructions will result in death or serious injury. |
Maximum Insertion/Removal Cycles
The TM5 System bus bases are designed to withstand up to 50 electronic module insertion/removal cycles.
NOTE: If electronic modules are inserted and removed from a bus base more than 50 times, the integrity of the electronic module-to-bus base contacts are subject to possible degradation. Be sure that the history of your electronic modules is known.
