Safety Guidelines
NOTE: Products with CE marks perform their required functions safely and adhere to relevant standards
as speciο¬ed by CE directives, provided they are used according to their intended purpose and that the
instructions in this manual are followed. The protection provided by the equipment may be impaired if
this equipment is used in a manner not speciο¬ed in this manual. A listing of our international afο¬liates is
available on our Web site at http://www.automationdirect.com.
WARNING: Providing a safe operating environment for personnel and equipment is your responsibility
and should be your primary goal during system planning and installation. Automation systems can
fail and may result in situations that can cause serious injury to personnel or damage to equipment.
Do not rely on the automation system alone to provide a safe operating environment. You should use
external electromechanical devices, such as relays or limit switches, that are independent of the PLC
application to provide protection for any part of the system that may cause personal injury or damage.
Every automation application is different, so there may be special requirements for your particular
application. Make sure you follow all national, state, and local government requirements for the
proper installation and use of your equipment.
Plan for Safety
The best way to provide a safe operating environment is to make personnel and equipment
safety part of the planning process. You should examine every aspect of the system to determine
which areas are critical to operator or machine safety. If you are not familiar with PLC system
installation practices, or your company does not have established installation guidelines, you
should obtain additional information from the following sources.
β’ NEMA β The National Electrical Manufacturers Association, located in Washington, D.C.,
publishes many different documents that discuss standards for industrial control systems. You can
order these publications directly from NEMA. Some of these include:
ICS 1, General Standards for Industrial Control and Systems
ICS 3, Industrial Systems
ICS 6, Enclosures for Industrial Control Systems
β’ NEC β The National Electrical Code provides regulations concerning the installation
and use of various types of electrical equipment. Copies of the NEC Handbook can often
be obtained from your local electrical equipment distributor or your local library.
β’ Local and State Agencies β many local governments and state governments have
additional requirements above and beyond those described in the NEC Handbook.
Check with your local Electrical Inspector or Fire Marshall ofο¬ce for information.
