Safety Guidelines

NOTE: Products with CE marks perform their required functions safely and adhere to relevant standards as
specified by CE directives provided they are used according to their intended purpose and that the
instructions in this manual are adhered to. The protection provided by the equipment may be impaired if this
equipment is used in a manner not specified in this manual. A listing of our international affiliates is available

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 control system installation
practices, or your company does not have established installation guidelines, you should obtain
additional information from the following sources.
• NEMA — 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:
• NEC — 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.
• Local and State Agencies — 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 office for information.
