TM5 System Terminal Blocks

Overview

The main features of the terminal blocks are:

Tool-free wiring with spring clamp push-in technology
Simple push-button wire release
Ability to label each terminal
Plain text labeling also possible
Test access for standard probes
Can be custom-coded

The following figure shows the TM5 System terminal blocks:

Number	Reference	Description	Color
1	TM5ACTB06	6-pin terminal block designed for 24 Vdc I/O modules and TM5SBET1 Transmitter module.	White
2	TM5ACTB12	12-pin terminal block designed for 24 Vdc I/O modules, Common Distribution Modules (CDM) and Transmitter modules.	White
3	TM5ACTB12PS	12-pin terminal block designed for 24 Vdc Power Distribution Modules (PDM), 24 Vdc Interface Power distribution Module (IPDM) and Receiver module.	Gray
4	TM5ACTB32	12-pin terminal block designed for AC and I/O relays modules.	Black
5	TM5ACTB16	16-pin terminal block designed for 24 Vdc I/O modules, Common Distribution Modules (CDM) and Transmitter modules.	White

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.

DANGER
	INCOMPATIBLE COMPONENTS CAUSE ELECTRIC SHOCK OR ARC FLASH Do not associate components of a slice that have different colors. Always confirm the compatibility of slice components and modules before installation using the association table in this manual. Verify 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.

General Characteristics

DANGER
	FIRE HAZARD Use only the correct wire sizes for the maximum current capacity of the I/O channels and power supplies. For 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). For 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.

WARNING
	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.

WARNING
	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.

2	Not applicable for TM5ACTB16.
3	Only for TM5ACTB16.

DANGER
	LOOSE WIRING CAUSES ELECTRIC SHOCK Do not insert more than one wire per connector of the spring terminal blocks unless using a double wire cable end (ferrule). 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.
