Safety Information

Important Information

NOTICE

Read these instructions carefully, and look at the equipment to become familiar with the device
before trying to install, operate, service, or maintain it. The following special messages may appear
throughout this documentation or on the equipment to warn of potential hazards or to call attention
to information that clarifies or simplifies a procedure.

35012676 10/2019 5

PLEASE NOTE

Electrical equipment should be installed, operated, serviced, and maintained only by qualified
personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of
the use of this material.

A qualified person is one who has skills and knowledge related to the construction and operation
of electrical equipment and its installation, and has received safety training to recognize and avoid
the hazards involved.

BEFORE YOU BEGIN

Do not use this product on machinery lacking effective point-of-operation guarding. Lack of
effective point-of-operation guarding on a machine can result in serious injury to the operator of
that machine.

UNGUARDED EQUIPMENT

 Do not use this software and related automation equipment on equipment which does not have

point-of-operation protection.

 Do not reach into machinery during operation.

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

This automation equipment and related software is used to control a variety of industrial processes.
The type or model of automation equipment suitable for each application will vary depending on
factors such as the control function required, degree of protection required, production methods,
unusual conditions, government regulations, etc. In some applications, more than one processor
may be required, as when backup redundancy is needed.

Only you, the user, machine builder or system integrator can be aware of all the conditions and
factors present during setup, operation, and maintenance of the machine and, therefore, can
determine the automation equipment and the related safeties and interlocks which can be properly
used. When selecting automation and control equipment and related software for a particular
application, you should refer to the applicable local and national standards and regulations. The
National Safety Council's Accident Prevention Manual (nationally recognized in the United States
of America) also provides much useful information.

In some applications, such as packaging machinery, additional operator protection such as point­of-operation guarding must be provided. This is necessary if the operator's hands and other parts
of the body are free to enter the pinch points or other hazardous areas and serious injury can occur.
Software products alone cannot protect an operator from injury. For this reason the software
cannot be substituted for or take the place of point-of-operation protection.

WARNING

6 35012676 10/2019

Ensure that appropriate safeties and mechanical/electrical interlocks related to point-of-operation
protection have been installed and are operational before placing the equipment into service. All
interlocks and safeties related to point-of-operation protection must be coordinated with the related
automation equipment and software programming.

NOTE: Coordination of safeties and mechanical/electrical interlocks for point-of-operation
protection is outside the scope of the Function Block Library, System User Guide, or other
implementation referenced in this documentation.

START-UP AND TEST

Before using electrical control and automation equipment for regular operation after installation,
the system should be given a start-up test by qualified personnel to verify correct operation of the
equipment. It is important that arrangements for such a check be made and that enough time is
allowed to perform complete and satisfactory testing.

EQUIPMENT OPERATION HAZARD

 Verify that all installation and set up procedures have been completed.
 Before operational tests are performed, remove all blocks or other temporary holding means

used for shipment from all component devices.

 Remove tools, meters, and debris from equipment.

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

Follow all start-up tests recommended in the equipment documentation. Store all equipment
documentation for future references.

Software testing must be done in both simulated and real environments.

Verify that the completed system is free from all short circuits and temporary grounds that are not
installed according to local regulations (according to the National Electrical Code in the U.S.A, for
instance). If high-potential voltage testing is necessary, follow recommendations in equipment
documentation to prevent accidental equipment damage.

Before energizing equipment:

 Remove tools, meters, and debris from equipment.
 Close the equipment enclosure door.
 Remove all temporary grounds from incoming power lines.
 Perform all start-up tests recommended by the manufacturer.

WARNING

35012676 10/2019 7

OPERATION AND ADJUSTMENTS

The following precautions are from the NEMA Standards Publication ICS 7.1-1995 (English
version prevails):

 Regardless of the care exercised in the design and manufacture of equipment or in the selection

and ratings of components, there are hazards that can be encountered if such equipment is
improperly operated.

 It is sometimes possible to misadjust the equipment and thus produce unsatisfactory or unsafe

operation. Always use the manufacturer’s instructions as a guide for functional adjustments.
Personnel who have access to these adjustments should be familiar with the equipment
manufacturer’s instructions and the machinery used with the electrical equipment.

 Only those operational adjustments actually required by the operator should be accessible to

the operator. Access to other controls should be restricted to prevent unauthorized changes in
operating characteristics.

Grounding of Installed Modules

General

The grounding of Modicon M340 modules is crucial to avoid electric shock.

Grounding Processors and Power Supplies

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

Ensure ground connection contacts are present and not bent out of shape. If they are, do not use
the module and contact your Schneider Electric representative.

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

UNINTENDED EQUIPMENT OPERATION

Tighten the clamping screws of the modules. A break in the circuit could lead to an unexpected
behavior of the system.

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

DANGER

WARNING

26

35012676 10/2019

All Modicon M340 modules are equipped with ground connection contacts at the rear for grounding
purposes:

These contacts connect the grounding bus of the modules to the grounding bus of the rack.
