There are several rules that must be followed when wiring a TM2 I/O module.
For modules that have more than one terminal block or connector that is identical, any of them can be potentially inserted into any socket.
Despite the indicators on the terminal blocks, connectors and modules, it is possible to incorrectly install the terminal blocks or connectors and create incorrect wiring.
Inserting a connector into an incorrect socket could cause unintended behavior of the application and/or present a risk of bodily injury.

ELECTRIC SHOCK OR UNINTENDED EQUIPMENT OPERATION |
|
Connect the terminal blocks to their designated location. |
|
Failure to follow these instructions will result in death or serious injury. |
NOTE: Clearly and uniquely label each terminal block and connector with an appropriate system of identification.

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH |
|
oDisconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires except under the specific conditions specified in the appropriate hardware guide for this equipment. oAlways use a properly rated voltage sensing device to confirm the power is off where and when indicated. oReplace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit. oUse only the specified voltage when operating this equipment and any associated products. |
|
Failure to follow these instructions will result in death or serious injury. |
The following rules must be applied when wiring the analog I/O modules:
oI/O and communication wiring must be kept separate from the power wiring. Route these 2 types of wiring in separate cable ducting.
oVerify that the operating conditions and environment are within the specification values.
oUse proper wire sizes to meet voltage and current requirements.
oUse copper conductors only.
oUse twisted-pair, shielded cables for analog, expert and/or fast I/O.
oUse twisted-pair, shielded cables for networks and field bus (CANopen, serial, Ethernet).
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
oUse shielded cables for all input, output and communication types specified above. oProperly ground the cable shields as indicated in the related documentation. oRoute communications and I/O cables separately from power cables. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
For more details, refer to Grounding.
The following table shows the cable types and wire sizes for removable screw terminal block:
Applying torque above the limit specified may damage the terminal screw or threads.

NOTICE |
|
INOPERABLE EQUIPMENT |
|
Do not tighten screw terminals beyond the specified maximum torque (Nm / lb-in.). |
|
Failure to follow these instructions can result in equipment damage. |
