TM3SAC5R / TM3SAC5RG Wiring Diagram

Introduction

These safety modules have a built-in removable screw or spring terminal block for the connection of inputs and outputs.

Wiring Rules

The 24 Vdc power supply must be rated Protective Extra Low Voltage (PELV) or Safety Extra Low Voltage (SELV) and fulfill the IEC/EN 60204-1 requirements. These power supplies are isolated between the electrical input and output circuits of the power supply.

WARNING

POTENTIAL OF OVERHEATING AND FIRE

oDo not connect the equipment directly to line voltage.

oUse only isolating PELV or SELV power supplies to supply power to the equipment.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING

LOSS OF CONTROL

Place a properly rated fuse on the primary input power line and on the outputs, as described in the related documentation.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Emergency Stop Wiring Diagram

Both the safety conditions and the start conditions must be valid before allowing the activation of outputs.

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not use either the monitored start or the non-monitored start as a safety function.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

This figure shows an example of emergency stop wiring to a TM3SAC5R• module:

S1: Emergency stop switch

S2: Start switch

(1): Safety outputs

(2): For automatic start, directly connect [Y1] and [Y2] terminals. For more information, refer to the TM3 Expansion Modules Programming Guide for your software platform.

(3): Fuses. Refer to electrical characteristics for fuse values.

(4): Non-safety related TM3 Bus communication with logic controller

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not use the data transferred over the TM3 Bus for any functional safety-related task(s).

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.
