This is the System Configuration Manual for DeviceNet Safety Systems. Heed the following items during
system construction to ensure that safety-related components are configured in a manner that allows the
system functions to operate sufficiently.
Risk Assessment
The proper use of safety devices described in this Manual as it relates to installation conditions and me-
chanical performance and functions is a prerequisite for their use. When selecting or using a safety device,
risk assessment must be conducted with the aim of identifying potential danger factors in equipment or fa-
cilities in which the safety device is to be applied, during the development stage of the equipment or facili-
ties. Suitable safety devices must be selected under the guidance of a sufficient risk assessment system.
An insufficient risk assessment system may lead to the selection of unsuitable safety devices.

ment
Safety Measures
When using safety devices to build systems containing safety-related components for equipment or facili-
ties, the system must be designed with the full understanding of and conformance to international stan-
dards, such as those listed below, and/or standards in related industries.

Typical related international standards: ISO/DIS 12100, Safety of Machinery -- Basic Concepts and
General Principles for Design
IEC 61508, Safety Standard for Safety Instrumented Systems (Functional Safety of Electrical/Elec-
tronic/Programmable Electronic Safety-related Systems)
Role of Safety Devices
The safety devices are provided with safety functions and mechanisms as stipulated in relevant standards,
but suitable designs must be used to allow these functions and mechanisms to operate properly inside sys-
tem constructions containing safety-related components. Build systems that enable these functions and
mechanisms to perform properly, based on a full understanding of their operation.

ated with Guards -- Principles of Design and Selection
Installation of Safety Devices
The construction and installation of systems with safety-related components for equipment or facilities must
be performed by technicians who have received suitable training.

Complying with Laws and Regulations
The safety devices conform to the relevant regulations and standards, but make sure that they are used in
compliance with local regulations and standards for the equipment or facilities in which they are applied.
•
Typical related international standards: IEC 60204, Safety of Machinery -- Electrical Equipment of
Machines
Observing Precautions for Use
When putting the selected safety devices to actual use, heed the specifications and precautions in this Man-
ual and those in the Operation Manuals that comes with the products. Using the products in a manner that
deviates from these specifications and precautions will lead to unexpected failures in equipment or devices,
and to damages that result from such failures, due to insufficient operating functions in safety-related com-
ponents.
Moving or Transferring Devices or Equipment
When moving or transferring devices or equipment, be sure to include this Manual to ensure that the person
to whom the device or equipment is being moved or transferred will be able to operate the system properly.
