Failure to follow these instructions will result in death or serious injury.
This equipment has been designed to operate outside of any hazardous location, and exclusive of
applications that generate, or have the potential to generate, hazardous atmospheres. Only install this
equipment in zones known to be free, at all times, of hazardous atmospheres.
POTENTIAL FOR EXPLOSION
Install and use this equipment in non-hazardous locations only.
Do not install and use this equipment in applications capable of generating hazardous atmospheres,
such as those applications employing flammable refrigerants.
Failure to follow these instructions will result in death or serious injury.
DANGER
DANGER
For information concerning the use of control equipment in applications capable of generating hazardous
materials, consult your local, regional, or national standards bureau or certification agency.
WARNING
LOSS OF CONTROL
The designer of any control scheme must consider the potential failure modes of control paths and,
for certain critical control functions, provide a means to achieve a safe state during and after a path
failure. Examples of critical control functions are emergency stop and overtravel stop, power outage
and restart.
Separate or redundant control paths must be provided for critical control functions.
System control paths may include communication links. Consideration must be given to the
implications of unanticipated transmission delays or failures of the link.
Observe all accident prevention regulations and local safety guidelines.
Each implementation of this equipment must be individually and thoroughly tested for proper operation
1
before being placed into service.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety Guidelines for the Application,
Installation, and Maintenance of Solid State Control" and to NEMA ICS 7.1 (latest edition), "Safety
Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive
Systems" or their equivalent governing your particular location.
WARNING
UNINTENDED EQUIPMENT OPERATION
Only use software approved by Schneider Electric for use with this equipment.
Update your application program every time you change the physical hardware configuration.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Before Starting
Read and understand this chapter before beginning the installation of your system.
Pay particular attention in conforming to any safety information, different electrical requirements, and
normative standards that would apply to your machine or process in the use of this equipment.
The use and application of the information contained herein require expertise in the design and
programming of automated control systems. Only you, the user, machine builder or integrator, can be
aware of all the conditions and factors present during installation and setup, operation, and maintenance
of the machine or process, and can therefore determine the automation and associated equipment and the
related safeties and interlocks which can be effectively and properly used. When selecting automation and
control equipment, and any other related equipment or software, for a particular application, you must also
consider any applicable local, regional or national standards and/or regulations.
Disconnecting Power
WARNING
REGULATORY INCOMPATIBILITY
Ensure that all equipment applied and systems designed comply with all applicable local, regional, and
national regulations and standards.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
All options and modules should be assembled and installed before installing the control system on a
mounting rail, onto a mounting plate or in a panel. Remove the control system from its mounting rail,
mounting plate or panel before disassembling the equipment.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Disconnect 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.
Always use a properly rated voltage sensing device to confirm the power is off where and when
indicated.
Replace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper
ground connection exists before applying power to the unit.
Use only the specified voltage when operating this equipment and any associated products.
Failure to follow these instructions will result in death or serious injury.
Programming Considerations
The products described in this manual have been designed and tested using Schneider Electric
programming, configuration, and maintenance software products.
WARNING
UNINTENDED EQUIPMENT OPERATION
Only use software approved by Schneider Electric for use with this equipment.
Update your application program every time you change the physical hardware configuration.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

EIO0000002015 02/2020
Installation Considerations
UNINTENDED EQUIPMENT OPERATION
Use appropriate safety interlocks where personnel and/or equipment hazards exist.
Install and operate this equipment in an enclosure appropriately rated for its intended environment and
secured by a keyed or tooled locking mechanism.
Use the sensor and actuator power supplies only for supplying power to the sensors or actuators
connected to the module.
Power line and output circuits must be wired and fused in compliance with local and national regulatory
requirements for the rated current and voltage of the particular equipment.
Do not use this equipment in safety-critical machine functions unless the equipment is otherwise
designated as functional safety equipment and conforming to applicable regulations and standards.
Do not disassemble, repair, or modify this equipment.
Do not connect any wiring to unused connections, or to connections designated as No Connection
(N.C.).
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTE: JDYX2 or JDYX8 fuse types are UL-recognized and CSA approved.
The M172 controllers are intended for Top Hat Section Rail (DIN rail) mounting, panel mounting, or wall
mounting.
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.
Before Starting
WARNING
WARNING
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.
For more information about enclosures, refer to the definition found in IEC 1000-4-2.
