Wiring Best Practices

Wiring Guidelines

The following rules must be applied when wiring M172 offer product range:

 I/O and communication wiring must be kept separate from the power wiring. Route these two types of

wiring in separate cable ducting.

 Verify that the operating conditions and environment are within the specification values.
 Use proper wire sizes to meet voltage and current requirements.
 Use copper conductors (required).
 Use twisted pair, shielded cables for analog, and/or fast I/O.
 Use twisted pair, shielded cables for networks, and fieldbus.

Use shielded, properly grounded cables for all analog and high-speed inputs or outputs and
communication connections. If you do not use shielded cable for these connections, electromagnetic
interference can cause signal degradation. Degraded signals can cause the controller or attached modules
and equipment to perform in an unintended manner.

WARNING

UNINTENDED EQUIPMENT OPERATION

 Use shielded cables for all fast I/O, analog I/O and communication signals.

 Ground cable shields for all analog I/O, fast I/O and communication signals at a single point
 Route communication and I/O cables separately from power cables.

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

Multipoint grounding is permissible if connections are made to an equipotential ground plane dimensioned

to help avoid cable shield damage in the event of power system short-circuit currents.

NOTE: Surface temperatures may exceed 60 °C (140 °F). Route primary wiring (wires connected to power
mains) separately and apart from secondary wiring (extra low voltage wiring coming from intervening
power sources). If that is not possible, double insulation is required such as conduit or cable gains.

LOOSE WIRING CAUSES ELECTRIC SHOCK

Tighten connections in conformance with the torque specifications.

Failure to follow these instructions will result in death or serious injury.

FIRE HAZARD

 Use only the recommended wire sizes for the current capacity of the I/O channels and power supplies.
 For relay output wiring up to 2 A, use conductors of at least 0.5 mm² (AWG 20) with a temperature

rating of at least 80 °C (176 °F).

 For relay output wiring of 3 A, use conductors of at least 1.5 mm² (AWG 16) with a temperature rating

of at least 80 °C (176 °F).

 For common conductors of relay output wiring of 9 A, or relay output wiring greater than 3 A, use

conductors of at least 2.0 mm² (AWG 12) with a temperature rating of at least 80 °C (176 °F).

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

Protecting Outputs from Inductive Load Damage

Depending on the load, a protection circuit may be needed for the relay outputs. Inductive loads using DC
voltages may create voltage reflections resulting in overshoot that will damage or shorten the life of output
devices.

Wiring Best Practices

DANGER

WARNING

CAUTION

OUTPUT CIRCUIT DAMAGE DUE TO INDUCTIVE LOADS

Use an appropriate external protective circuit or device to reduce the risk of inductive direct current load
damage.

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

Choose a protection circuit from the following diagrams according to the power supply used. Connect the
protection circuit to the outside of the controller or relay output module.

If your controller or module contains relay outputs, these types of outputs can support up to 240 Vac.
Inductive damage to these types of outputs can result in welded contacts and loss of control. Each
inductive load must include a protection device such as a peak limiter, RC circuit or flyback diode.
Capacitive loads are not supported by these relays.

WARNING

RELAY OUTPUTS WELDED CLOSED

 Always protect relay outputs from inductive alternating current load damage using an appropriate

external protective circuit or device.

 Do not connect relay outputs to capacitive loads.

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

Protective circuit A: this protection circuit can be used for both AC and DC load power circuits.

C Value from 0.1 to 1 μF

R Resistor of approximately the same resistance value as the load

EIO0000002015 02/2020 33

Wiring Best Practices

Protective circuit B: this protection circuit can be used for DC load power circuits.

Use a diode with the following ratings:

 Reverse withstand voltage: power voltage of the load circuit x 10.
 Forward current: more than the load current.

Protective circuit C: this protection circuit can be used for both AC and DC load power circuits.

In applications where the inductive load is switched on and off frequently and/or rapidly, verify that the
continuous energy rating (J) of the varistor exceeds the peak load energy by 20 % or more.

NOTE: Place protection devices as close to the load as possible.

Special Handling Considerations

Care must be taken to avoid damage from electrostatic sources when handling this equipment. In particular
exposed connectors and, in some cases, exposed printed circuit boards are exceptionally vulnerable to
electrostatic discharge.

UNINTENDED EQUIPMENT OPERATION DUE TO ELECTROSTATIC DISCHARGE DAMAGE

 Keep equipment in the protective conductive packaging until you are ready to install the equipment.
 Only install equipment in approved enclosures and / or locations that prevent casual access and

provide electrostatic discharge protection.

 Use a conductive wrist strap or equivalent field force protective device attached to an earth ground

when handling sensitive equipment.

 Always discharge yourself by touching a grounded surface or approved antistatic mat before handling

the equipment.

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

Analog Inputs-Probes

Wiring Best Practices

Temperature probes have no connection polarity and can be extended using a normal bipolar cable.

The extension of the probes wiring influences the electromagnetic compatibility (EMC) of the instrument

Verify the polarity for probes which have a specific connection polarity.

NOTICE

INOPERABLE EQUIPMENT

Verify all wiring connections before applying power.

Failure to follow these instructions can result in equipment damage.

Do not power any connected devices that are externally powered without also applying power to the M172.

NOTICE

INOPERABLE EQUIPMENT

Ensure that the controller has power applied when applying power to other connected and externally
powered devices.

Failure to follow these instructions can result in equipment damage.

Signal leads (probes, digital inputs, communication, and the electronic supply) must be routed separately
from power cables.

Power Supply and Field bus Wiring Restriction For Non Isolated Controllers and Expansion Modules

TM172P••28• / TM172P••42• / TM172E••R power supply inputs are not isolated. If you connect the GND
connection of the RS-485 network or the CAN expansion bus across multiple controllers, you must use
separate, isolated power supplies. Alternatively, if you are interconnecting the equipment to a single power
supply, do not connect the RS-485 or CAN GND signal. Pay special attention when connecting serial lines.
Miswiring may lead to inoperable equipment.

Analog Inputs

Overview

Controllers analog inputs are identified as AI1…AIx.

The inputs are configurable in pairs, AI1- AI2 is the first pair, AI3-AI4 is the second pair, and so on, up to
the last pair. Both AIs of a pair must be configured in order to belong to the same type group.

Using the parameter Cfg_Aix, an analog input AIx can be configured to acquire a signal by a physical
resource (probe, digital input, voltage/current signal) as specified in the following table:
